A Research On Receiving Technology Of Space-born Laser Warning

The background of this paper is the application of the space-borne laser warning. The research on the receiving technology of space-borne laser warning is implemented with the receiving object of the beacon laser or illuminate laser of the laser weapon system and the early warning of anti-satellite laser weapon system is realized. The purpose is promoting the laser threat sensing capability of the satellite system, and then improving the evasion and surviving capability. It can supply reference to the receiving technology design of the satellite laser warning system and optimize reasonably the comprehensive performance of the following laser warning system reasonably.Firstly, the main factors effect on receiving technology of the space-borne laser warning are analyzed, involving photoelectric detector, operational amplifier and amplifying circuit. The results show that the main noise resources are the noise of the operational amplifier. Comparing the advantages and disadvantages between the different biasing circuit and receiving circuit combined with different operational amplifier can supply reference to the receiving technology design of the space-borne laser warning device. Then the simulation model of the circuit of photoelectric detector (GT101-Φ2) is built based on the theory analyzing and experimental verifying correction. Finally the feasibility of con-channel detecting with the pulse and continual laser signal is analyzed in theory. Then verify the correctness of theoretical analysis via experiments.
