Types Of Radar – Information And Facts

types of radar

Radar is an electronic sensing device that sends out high-frequency radio waves and detects the reflected signals. It can detect objects as far as several hundred meters away. There are many different types of radar with different uses.

Radar is used by the military for detecting enemy planes, ships and submarines. It is also used by police, fire departments and private individuals.

In this article, we will discuss the most common types of radars and what they are used for. We hope this article will be useful for you.

Bistatic Radar


Bistatic radar is a passive radar system that detects objects based on the difference in the time it takes for an echo signal to reach two receivers. It can detect objects at a much greater range than standard radar. This allows you to see things that are hidden from the naked eye.

A common use for this technology is to help guide an airplane to a safe landing. The plane would send out a signal and then receive back an echo signal that indicated the distance to the object reflecting the signal.

Doppler Radar

Doppler radar

A doppler radar is a device that uses the principle of doppler effect to detect the speed of an object approaching or receding from you. It does this by transmitting a high-pitched tone (usually, a sine wave) and then measuring the time it takes for that same tone to be reflected back to the radar unit. The difference in the time it takes for the reflected tone to return is then used to determine the speed of the approaching or receding object.

This allows the radar to distinguish between different types of objects. For example, if an animal is approaching or receding from you, the radar will measure a much higher frequency of returned tones than it would if the object was a car. Therefore, the radar can easily tell the difference. This makes doppler radars great for detecting the approach or departure of vehicles at highway speeds.

Monopulse Radar

Monopulse radar is a type of electronic scanning radar that was originally developed by a Canadian company, Radarscan Inc. It was acquired by a California-based company called Pulse Technology, Inc. in 1996. The technology was licensed to a number of other companies, including Harris Corporation.

Monopulse radar works on the same principal as pulsed radar, except that monopulse radar uses a single continuous wave rather than a series of pulses. This means that it can detect a wider range of objects than pulsed radar, even at greater distances.

It’s often used for automotive collision avoidance because of its ability to detect an object at very high speeds. It can also be used for air traffic control and to guide missiles.

Passive Radar

Passive Radar

A passive radar gun is an electronic device that measures the speed of a vehicle using the Doppler effect. The radar gun sends out a continuous wave signal that bounces off any objects in its path. The frequency of the reflected wave is slightly different than the frequency of the transmitted wave. This causes a slight shift in the radar gun’s receiving signal. 

If there are no obstacles between the radar gun and the vehicle, then the reflected wave will be at the same frequency as the transmitted wave. However, if there is an obstacle in the radar gun’s line of sight, then the reflected wave will be at a lower frequency than the transmitted wave. The radar gun measures the difference in frequency to determine the size of the object that caused the reflection.

Radar guns are widely used by police departments to enforce speed limits and to catch speeders. They are also used by insurance companies to determine whether or not to raise your premiums because you drive dangerously. Passive radar guns are small, portable devices that can be attached to the top of a car, motorcycle, or even a bicycle.

Instrumentation Radar

An instrumentation radar is a very high-tech device that is often used in conjunction with a computer. It is basically a sophisticated radar that can detect objects at a much greater distance than is possible with a conventional radar. This allows the driver to see things that are not visible to the naked eye.

The way it works is that a beam of radio waves is beamed out into the air. Anything that reflects the radio waves back to the instrumentation radar is detected. An ordinary radar has a range of about 1,000 feet. However, an instrumentation radar can detect objects that are many miles away.

This allows the driver to see things that are not visible to the naked eye. For example, it can detect deer that are hundreds of yards away. It can also detect vehicles that are hundreds of yards away. This is especially important if the road you are traveling on has a lot of curves and hills. If you don’t have your vehicle equipped with this type of radar, then you are essentially blind when driving in these types of areas.

Weather Radars

Weather Radars

A weather radar is an instrument that displays on a screen a picture of the weather conditions around you. It does this by sending out radio waves into the atmosphere and then analyzing the reflections off of these waves as they return to the antenna on the weather radar.

The information gathered from the analysis of these reflected waves is displayed on the screen as a map of the area around you. This gives you a graphical display of the weather conditions around you. You can see areas of precipitation (rain, snow, hail, or sleet) and you can also see areas of low pressure (which indicate clouds and sometimes a location of a tropical disturbance).

Mapping Radars

A mapping radar is a device used by a navigator to determine the distance and bearing (instrumental direction) of a radio signal, such as that from a radar detector. The navigator plots this information on a map and can determine the location of the source of the detected signal.

Mapping radars are usually carried by aircraft and are used for air defense. Some mapping radars are ground-based and are used for counter-terrorism or criminal investigations. A mapping radar is different from a surveillance radar which detects only the presence of an object, and not its nature.

Navigational Radars

Navigational radars

A navigational radar is a device that uses radio waves to detect and measure the range, direction, and sometimes the speed of an object such as a boat or airplane. A navigational radar is different from an ordinary radio receiver in that it has a very narrow beam of radio waves. This allows the navigational radar to detect objects at great distances and also to distinguish between multiple targets. It can also detect the size of the target.

Navigational radars are used on boats to help guide them to their destination. They are also used on land vehicles to help avoid collisions. They are installed on the roofs of many trucks and cars. These days, they are also found on some airplanes.

Basic Pulse Radar

A basic pulse radar is a low-cost, easy-to-use tool that will help you locate hidden objects like metal, wood, and even people. It’s perfect for detecting and locating things that are hidden behind walls, under floors, inside furniture, and just about anywhere else. You can use this tool to find stuff that is hard to see or that is not easily detected by other means.

A pulse radar works by sending out a high-pitched sound wave into the area to be searched. When the wave hits an object, it reflects back to the transmitter/receiver. The difference in time between when the wave is sent out and when it comes back is what determines what is being detected. 

If it is a metal object, then the reflected wave will be slightly delayed because of the metal’s density. A wooden object will reflect the wave slightly faster than metal. An object that is made of other materials will reflect the wave at a rate similar to that of wood. This tool is easy to use and only requires one hand.

Moving Target Indication Radar

Moving Target Indication Radar

A moving target indication (MTI) radar system is an advanced type of radar used by police to detect and track moving vehicles. It has a large antenna located on top of a tall pole which transmits radio waves into the sky. When the waves hit an object such as a vehicle, they are reflected back to the radar antenna. The antenna then detects this reflected energy and calculates the speed and direction of the target.

This allows the operator to see on a digital display exactly where the target is and how fast it is traveling. This is extremely useful for law enforcement agencies who need to know the location of all the bad guys as well as the good guys!

Unmodulated Continuous Wave Radar

Unmodulated continuous wave radar is a radar system that transmits a continuous wave signal. This type of radar works on the same principal as a sonar system. It sends out a steady signal that reflects off of objects in its path. The difference is that this radar does not use sound to detect objects. It uses electromagnetic waves.

Unmodulated continuous wave radar is used for a variety of purposes. For example, it is often used for automotive safety applications. In an automotive application, the radar would be mounted on the front of the vehicle and would continuously scan the area in front of the vehicle for objects such as other vehicles, pedestrians, and obstacles.

Unmodulated continuous wave radar is also used in air traffic control. This type of radar is often mounted on the top of a tower near an airport. It is used to detect aircraft that are too high or too low in the sky to be seen with the naked eye. It also detects any aircraft that might be approaching the airport that is not identified by the control tower.

Frequency Modulated Continuous Wave Radar

FM CW radar uses a continuous wave signal with a very narrow bandwidth, which is modulated by the radar transmitter’s intermediate frequency. This causes the transmitted signal to appear as a wideband signal with a series of narrow sidebands superimposed on it. These sidebands represent the individual frequencies of the original CW signal.

The receiver is a very high-Q tuned circuit that responds only to the particular sideband representing the desired signal. The detector then demodulates the detected signal and produces an audio signal that represents the original CW signal.


How is radar used today?

Radar is used in a wide variety of applications, from police traffic speed detection to weather radars and military applications.

However, one of the most common uses of radar is for the detection of aircraft. As you might guess, the primary use of civilian aircraft is for air travel, but a surprising number of small aircraft are also operated commercially.

Which wave is used in radar?

Any wave will do. You can use any wave to make a radar system, but the waves used in radar are usually microwaves. Missiles use infrared, but you can’t do that for detection of weather.nSo, what we’re going to do here is detect rain using microwaves. 

What is the maximum range of radar?

Radar can detect objects at distances of several tens of kilometres. However, the effective range of a typical radar installation is only about 10-15 km. This is because the signal transmitted by the radar has to pass through the Earth’s atmosphere and be reflected off objects on the other side of the planet before it gets to your antenna. Therefore, if an object is further away than about 15 km, it will not be detected by your radar.

What can the radar detect?

The radar can detect solid objects such as trees, houses, vehicles, birds, etc. It can also detect “radar-reflecting” water in lakes, rivers and oceans. When it detects these objects, the radar displays a blip on the screen which is an image of what that object looks like. This allows you to see what’s going on even if you are some distance away.


Radar is an electronic device that is used to detect objects that are very far away. When you are driving at night, you need to be very careful because many other drivers don’t have the skills to see you when you are using your radar. In most cases, if you use your radar correctly, you will be able to avoid dangerous situations.

But, many people do not know how to use radar correctly. If you are one of them, you should learn how to use it right away. We hope that after reading the above article, you will learn how to use radar properly and safely.
