Power monitor for radar system
First Claim
1. A method for detecting a power-reducing coating (5) on a radome (2) of a radar system, said method comprising:
- (a) feeding to a receiver of said radar system a monitor signal comprising a modified part of electromagnetic radiation emitted by said radar system and modified by interaction with said power-reducing coating; and
(b) evaluating said monitor signal, whereby said power-reducing coating is detected.

Abstract
A method and corresponding devices for monitoring the performance of a radar system (2, 4) which is equipped with a shield 2 (radome) 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).

12. A device for detecting a power-reducing coating (5) on a radome (2) of a radar system, wherein said device comprises
one or more elements (3, 7, 9) for modifying part of the irradiated radar radiation and transmitting this part to a receiver device (4), each element (3, 7, 9) being arranged in such a way that the coating (5) present on the radome (2) influences the modified radiation, and means for evaluating the modified part of the irradiated radar radiation received by the receiver device (4).

21. A device for detecting a power-reducing coating (5) on a radome (2) of a radar system, wherein said device comprises
at least one resonant structure (7) adapted to resonating at the frequency of the radar and experiencing post-oscillation for such a period that the decay of the oscillations occurs in the sensitive time range of the radar system, and arranged in such a way that the coating (5) present on the radome (2) influences the post-oscillations, and means for evaluating a drop in signal components received by the receiver device (4).

22. A device for detecting a power-reducing coating (5) on a radome (2) of a radar system, wherein said device comprises
modulator means (9) arranged to modulate radar signals reflected from said radome (2) and to reflect the modulated radar signals back to the radome, a receiver device (4) for receiving said reflected modulated radar signals said modulator means being arranged in such a way that the coating (5) present on the radome (2) influences the modulated radar signals, and means for evaluating the modulated radar signals received by the receiver device (4).
