Study on the method of RF filtering for the new polarization radar
The terminal guidance radar is faced with the interferences including the passive chaff and the active off-board decoy. It is effective to adopt polarization signal processing to suppress such interferences. Traditional polarization signal processing is finished in the video frequency, and the radar receiver would be saturated and disabled when the interference is strong enough. For this, a new adaptive polarization agile microwave network is proposed in order to solve the problem in this paper. The microwave network can suppress the interferences in the RF band before the interferences enter into the receiver, so we call it RF polarization filter. The structure and theorem of the RF polarization filter are given and the estimates of the interference polarization parameter arc also discussed.
