摘　　要：对于中程距离的测量，从测量速度、精度和可靠性的折衷方面来讲，相位式激光测距法优于其它的测距法。给出了非合作目标相位式激光测距系统的接收光功率表达式，研究了根据信噪比确定所需的接收光功率，从而估计测程的方法。In terms of speed, accuracy and reliability for medium range measurement, phase shift laser rangefinder is superior to other methods. The expression of received laser power in phase shift laser rangefinder with non cooperative target is presented. Method of achieving the received power based on the signal to noise ratio, further estimating the range, is discussed.
