中文说明： 激光雷达是以发射激光束探测目标的位置、速度等特征量的雷达系统。从工作原理上讲，与微波雷达没有根本的区别：向目标发射探测信号(激光束),然后将接收到的从目标反射回来的信号(目标回波)与发射信号进行比较,作适当处理后,就可获得目标的有关信息,如目标距离、方位、高度、速度、姿态、甚至形状等参数,从而对飞机、导弹等目标进行探测、跟踪和识别。程序为Matlab仿真FMCW激光雷达信号。
English Description：
Lidar is a radar system which detects the position, velocity and other characteristics of the target by emitting laser beam. In principle, there is no fundamental difference with microwave radar: transmitting detection signal (exciting beam) to the target, then comparing the received signal (target echo) reflected from the target with the transmitted signal, and after proper processing, the relevant information of the target can be obtained, such as target distance, azimuth, altitude, velocity, attitude, even shape and other parameters, So as to detect, track and identify aircraft, missiles and other targets. Matlab is used to simulate FMCW lidar signal.
