In radar terminology, a “track” refers to the continuous monitoring and recording of the position, velocity, and other parameters of a detected object over time. When a radar system detects a target, it initiates a track by associating and continuously updating the target’s position, typically in terms of azimuth, elevation, and range. The radar system calculates the target’s trajectory based on successive radar returns, allowing it to predict future positions and movements. Tracks are essential in radar operations to maintain situational awareness, effectively guide weapon systems and coordinate air traffic or military operations.
A tracking radar system is used to monitor and maintain tracks on objects of interest, such as aircraft, ships, vehicles or missiles. Unlike search radars that scan large areas for targets, radar tracking focuses on individual or selected targets to provide precise and continuous updates on their positions, velocities and other relevant parameters. Radar system tracking is an integral part of military operations for target acquisition, missile guidance, fire control and air traffic management. They are also used in civilian applications such as weather monitoring, satellite tracking and surveillance.
Track While Scan (TWS) is a radar mode of operation that allows the radar system to simultaneously track multiple targets while continuously scanning the surrounding airspace or terrain for new targets. In TWS mode, the radar divides its time between scanning for new targets and updating tracks on existing targets. When a target is detected and tracked, the radar continues to search for additional targets without interrupting the tracking process. TWS mode improves radar efficiency by allowing operators to simultaneously monitor and manage tracks, providing complete situational awareness and flexibility to respond to changing threats or operational requirements.
