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.本程序为FMCW激光雷达matlab程序，包括调频非线性校正等(Laser emitting a laser beam radar detection is the target position, velocity, volume and other characteristics of the radar system. From the working principle, and there is no fundamental difference between the microwave radar: transmitting to the target detection signal (laser beam), then the received signal reflected from the target (target echo) is compared with the transmitted signal, after appropriate treatment , you can get information about the target, such as the target distance, direction, altitude, speed, attitude, and even the shape and other parameters to the aircraft, missiles and other target detection, tracking and identification. This program is FMCW laser radar matlab procedures, including FM nonlinear correction.)
