Surface motion radar operates at a specific rotation speed, generally varying depending on the intended design and use of the system. This rotation speed determines how often the radar beam scans the area of interest. For most surface motion radars, this speed varies from several revolutions per minute (rpm) to around 12-15 rpm in more advanced systems.
This rotation allows the radar to continuously scan the designated area, providing real-time information on the movement of objects on the ground or water surface.
Surface motion radar operates in specific frequency bands allocated for radar applications. The frequency of surface motion radar is typically in the S-band (2-4 GHz) or L-band (1-2 GHz) of the electromagnetic spectrum. These frequencies are chosen for their ability to penetrate various weather conditions and provide precise detection and tracking of objects on the ground or water surface.
The choice of frequency band often depends on factors such as radar range requirements and the environmental conditions where the radar is deployed.
Radar rotation speed refers to the speed at which the radar antenna rotates as it scans its surroundings. For surface motion radar, this rotation speed is crucial because it determines the update rate and coverage area of the radar. Modern radar systems used for surface movement typically have rotational speeds that vary from approximately 5 to 15 revolutions per minute (rpm).
Higher rotation speeds enable faster updates on the position and movement of objects such as aircraft, vehicles and ships on the land or water surface.
Surface motion radar is primarily used to monitor and manage the movement of objects on airport runways, taxiways and apron areas. Its main function is to improve safety by providing real-time information on the position, speed and trajectory of aircraft, vehicles and other objects on the ground.
This radar technology helps air traffic controllers and ground personnel more effectively coordinate movements, prevent collisions and ensure efficient use of airport infrastructure. Surface motion radar also contributes to overall airport operations by improving ground traffic management, reducing delays and supporting the safe and orderly flow of air traffic
