In this article, we will teach you What are the two main types of radar?, What are the two modes of radar?
Types of radar (radar types, types of radars, type of radar)
The two main types of radar are primary radar and secondary radar. Primary radar works by transmitting radio waves and detecting reflections (echoes) from objects, such as planes or ships. It provides information on the position, range, azimuth (direction), and sometimes altitude of targets. Primary radar is widely used in air traffic control, military surveillance and weather monitoring due to its ability to detect objects independently of their cooperation.
Secondary radar, also known as secondary surveillance radar (SSR), works differently by transmitting interrogations to aircraft equipped with transponders. These transponders respond with coded information, such as aircraft identification (Squawk code) and altitude. Secondary radar enhances air traffic control capabilities by providing additional data to identify and track aircraft, improving the safety and efficiency of occupied airspace.
What are the two modes of radar?
The radar operates in two main modes: pulse radar and continuous wave (CW) radar. Pulse radar transmits short pulses of radio waves and measures the time it takes for the pulses to return after reflecting off objects. This allows accurate determination of the distance to targets (range) and their relative speed. Pulse radar is commonly used in applications requiring precise range measurements, such as military surveillance, weather monitoring, and traffic control.

Continuous wave (CW) radar, on the other hand, emits a continuous wave of radio frequency without interruption. It detects frequency changes caused by the Doppler effect when the wave reflects off moving objects, such as vehicles or airplanes. CW radar is suitable for measuring the speed of moving targets (Doppler radar) and is used in applications such as speed enforcement, radar guns and vehicle collision avoidance systems.
The two main functions of radar are detection and tracking. Detection involves identifying the presence of objects in the radar coverage area by detecting reflected radio waves (echoes). Radar systems use various techniques to distinguish between targets and background noise, ensuring reliable detection of objects such as aircraft, ships, vehicles or weather phenomena.
Tracking, the second main function of radar, involves continuous monitoring of the position, speed and sometimes other parameters (such as altitude or heading) of detected targets over time. Radar tracking systems use data from successive radar scans to predict future positions and movements of tracked objects, allowing operators to maintain situational awareness, guide air traffic, monitor military threats or to accurately track weather patterns. Tracking is essential to maintaining the safety, efficiency and effectiveness of radar applications in various sectors, from transportation and defense to meteorology and surveillance.
