A radar repeater system and a radar repeating method

摘要

The invention relates to a radar repeater system for mitigating a degraded radar zone behind a radar attenuating obstacle. The system comprises a receiving antenna for receiving a radar signal transmitted by a radar system. The system further comprises a transmitting antenna being arranged for retransmitting a radar signal forwarded to the transmitting antenna. The system also comprises an intermediate circuit interconnecting the receiving antenna with the transmitting antenna for forwarding the received radar signal to the transmitting antenna. The receiving antenna, the transmitting antenna and the intermediate circuit form a radar repeater module for repeating a radar signal transmitted by the radar system. Further, the intermediate circuit is arranged for dynamically applying a phase shift to the received radar signal.
