Research Of Target Detection System For Laserproximity Fuze

Laser proximity fuse plays a significant role in the system of weapon aiming and positioning, because of its merits of high positioning precision, strong anti-interference ability and so on. There has a higher demand to the positioning precision of laser proximity fuse as the steady improvement of battle weapons, war size and the increasing complicated war environments.It analyzed the feature of laser target scattering and the principles of laser ranging and put forward a design method of high precision laser proximity fuse based on the PIC chip in this essay. This proposal designed the fuse system organization and did functional analysis of each part; meanwhile the design put emphasis on the high security of the system. It made a detailed design of laser excitation source; generally divide the fuse system into several parts including Laser transmitting system, laser receiver system, signal processing and executive circuit; and build blocking design of each component.
