Abstract

The laser-beam riding guidance system controls the way a missile flies and hits a target by encoded laser information field. This paper discusses the spatial encoding method of the modulating disk in the laser beam riding guidance system and designs a light field modulation optical system for the transmitter of the laser beam riding guidance system. The reshaped laser beam can be projected into the internal and external code channels of the modulating disk, thus generating an encoded information field which will be used to control the flight of a missile. Besides, this paper designs a distributed photo detector light field collection system to simultaneously test the light field modulation status of the information field. This system is composed of modules including a pinhole aperture array, a PIN array, a signal processing electric circuit and a data collecting and processing module. The result demonstrates the accuracy and feasibility of the modulated light field test carried out with this system.
