Through the analysis of laser beam steering guidance principle, a pulse generator based on complex programmable logic device (CPLD) and single chip microcomputer was designed and the generation of electrical pulse signal consistent with the laser beam steering light field information rule was achieved. The design of a fast switching drive circuit and a power control circuit to amplify the electric pulse signal to drive a high-response quasi-laser diode effectively simulates the laser beam steering light field information, so as to solve the laser beam guidance weapon receiving system The receiver sensitivity, as well as yaw and pitch guidance accuracy parameters of indoor non-contact testing provides an effective method. The error of the simulation test device is analyzed, and a method of reducing the error is proposed.
