What is TWS in radar?
In Radar, TWS stands for track-while-scan. This mode allows the radar to scan a large area for targets while simultaneously tracking the positions and movements of multiple targets. By periodically scanning the area and updating information on each tracked target, TWS provides complete situational awareness. It is commonly used in military and civilian radar systems to monitor and manage multiple objects, such as aircraft or ships, within the range of the radar.
In aviation, TWS (track-while-scan) is a radar mode used by aircraft to detect, track and monitor multiple airborne targets simultaneously. This mode allows the radar to continuously scan a designated airspace while keeping track of the positions, speeds and trajectories of multiple aircraft. TWS improves pilot situational awareness by providing real-time updates on potential threats or other nearby aircraft, making it crucial for air traffic control, military operations and security systems. collision avoidance.
Tracking methods in radar include several techniques to monitor and update the position and movement of targets. These methods include:
Track-while-scan (TWS): This method involves scanning a large area while continuously tracking multiple targets in that area. The radar periodically updates information about each target, providing a complete overview of the environment.
Single Target Track (STT): This method focuses on a specific target, providing detailed and continuous updates on its position, speed and trajectory. It sacrifices broader situational awareness for highly precise tracking of a single target.

Continuous Wave (CW) Radar: This method transmits a continuous signal rather than pulses. It is often used to measure the speed of a target using the Doppler effect.
Pulse Doppler Radar: This method combines pulse radar techniques with the Doppler effect to measure both the range and speed of targets, providing detailed information about moving objects.

Monopulse Radar: This method uses multiple beams to track the position of a target more precisely. It compares signals received in different beams to calculate the target angle and improve tracking accuracy.
Kalman Filtering: This is a mathematical technique used in radar systems to predict and update the position of a target based on its previous positions and velocities. It helps smooth the target track and reduce errors caused by noise and other factors.
