摘要 针对宽脉冲相干激光雷达信号处理遇到测距精度差的问题,将脉冲压缩算法引入到相干激光雷达信号处理中。文章首先对脉冲压缩相干激光雷达测距原理和精度进行理论分析,通过仿真实验验证该理论正确性。仿真结果表明采用脉冲压缩的信号处理方法可以实现测距,并且可以提高测距距离和测距精度,为以后相干激光雷达测距提高作用距离与测距精度提供了重要的理论依据。 The pulse compression algorithm was introduced into the coherent laser radar signal processing,whichsolved the problems of poor accuracy.Firstly,the theory and accuracy of pulse compression coherent laser radar ran-ging are analyzed;the theory correctness is proved through the simulation results.The simulation results also showthat ranging can be realized by using pulse compression signal processing method,and ranging distance and accuracycan be improved,it is important for the coherent laser radar ranging distance and accuracy.
