Experimental module of the 10.6 micron laser rangefinder with the heterodyne detection and pulse compression
Abstract
The principles of operation and experimental results of a module of a heterodyne CO2 laser rangefinder with signal compression are presented. After compression, the signal duration is about 85 ns. The transmitter dispersive line and receiver dispersive line ensure the signal compression and allow measurements of the distance from the target and its radial velocity to be obtained. The CW laser output power is 3 W. In order to obtain a S/N of 50, a detection rate of 90 percent, and a false alarm probability of 0.001, it is suggested that about 7000 signals need to be summed.
