Abstract
Hie mechanism about range-Doppler coupling effect based on time and spectrum characteristic to LFM matched filter is analyzed in this paper. When a LFM pulse passed through the matched filter, the output signal is compressed and delayed. An ranging error correction model is proposed because of range-Doppler coupling effect. After space target distance-measuring data analyzing and computer simulating, the actual result of this new error correction model of LFM range measure is certificated as the conclusion of this paper. The issues matched filter compression delay time, the variety of Doppler frequency which is input matched filter network, positive or negative slope LFM ranging error correction etc should pay more attention to in engineering application is also mentioned here.关键词
