| Abstract: | 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. |
