摘要
分析了相干激光雷达线性调频脉冲的产生及其信号处理过程，讨论了该雷达信号体制的处理方法和结果。计算了采用匹配滤波和加权处理结果，对于1MHz／μs的调制速率信号的结果表明，激光相干雷达的测速和测距精度分别可达0.04m／s和0．57m.
The chirp coherent ladar signal and its processing is analyzed. Matched filtering and weighting result are of use for computating the 1MHz/Us chirp-pulse velocity signal. It is proved. that the range and velocity resolutions of the ladar are reaching to 0. 57m and 0. 04m/s respectively.
