1. a kind of method that frequency modulated continuous wave radar direct wave inhibits, comprising:

  • The method being isolated by antenna, makes to enter the direct-path signal power in the echo-signal of receiving channel and connects lower than radarReceive the P of the low-noise amplifier of front end-1Value;

    AndIt is received using frequency modulation removal and direct-path signal is converted to fixed frequency, make the direct-path signal in echo-signal and useful timeWave signal separates on frequency domain, and the filtering processing of direct-path signal is carried out to echo-signal.
