摘要
针对现有的单频率脉冲相干探测激光雷达的高精度测量矛盾,研究采用线性调频脉冲压缩的方式实现相干激光雷达对目标的高精度测距和测速。文中介绍了线性调频脉冲压缩的原理并给出了仿真结果,并结合相干激光雷达系统的特点,并对系统的实现方式问题进行了探讨。
Aiming at the existing high precision measuring spear of single frequency pulse coherent lidar,the method of linear frequency modulation pulse compression is used to realize high-precision ranging and velocity measurement of target.The principle of linear frequency modulation pulse compression is introduced and the simulation results are given in the paper.Combining with the characteristics of system,the realization method of system is discussed.
