Simulation Test System For Laser Beam Riding Guidance

A technique of testing the simulational laser guidance is studied. The arrangement and design principle of a steeering laser guidance system are described. According to the practical application of the system, the experimental simulational steer-head is set up. The simulational steer-head is made up of optical system and processing circuit. The structure of testing polarized light with optical receiving system is designed. A single chip microcomputer is used as the core chip in the processing circuit. The software and hardware of the simulational processing circuit is designed. The hardware of the system including the photoelectric converter, preamplifier, filter, A/D converter, data processing and driving step motor are made up. Moreover, the filter in the hardware system is compared and analysed by the software and the hardware. The photoelectric testing module is designed. The filter is tested in simulated condition and the result basically accord with the experiment demands. The process procedures of the simulational processing circuit is designed in the software of the system. In the condition of laboratory, the simulational optical system and the simulational processing circuit are built. The errors possibly existing in the experiment are analysed.
