Power monitor for radar system

摘要

A method and corresponding devices for monitoring the performance of a radar system (2, 4) which is equipped with a shield 2 (radom) to protect it against weather influences are described. For this purpose, a part of the radiated radar signal is modified and fed as a monitor signal to the reception system after interacting with a coating (5) which is possibly present on the radom (2). Influences of a damping or reflecting coating (5) on the radom (2) change the monitor signal. By analyzing these changes it is possible to draw conclusions about the coating of the damping or reflection of the radar signals which is caused by the coating (5).
