Title Study on the pulse laser irradiator for simple guidance
Abstract For the need of semi-active laser homing simple non-imaging-guidance, the study on cluster simple guidance ammunition detonating control technology based on laser information transmission is start, and is carried out to improve the ammunition precision strike ability.
In the sections of the design theories, the dissertation analyzes the working principle and coding theory of laser irradiator and designs a pulse laser irradiator for simple guidance. In the sections of the technique implementation, Using the driving circuit mode of direct power and MOSFET gating, the pulse laser irradiator can work Continuously and normally. Using the pulse coding circuit based on FPGA, the pulse laser is coded. Using laser optical path based on Inverted telescope, the laser beam can be compressed and collimated. Using the information processing circuit based on single-chip, the laser irradiator can communicate with the fire control system.
In this dissertation，the light spot irradiating on target at the 300m distance is 1.5m x 1.5m，and transmit the information to the incoming the laser simple guided ammunitions，to provide the possibility for the precision strike.
