Paper Abstract

Laser fuze has been widely used in a variety of large-caliber ammunitions, such as missile, aerial bomb and rocket bomb, due to its typical advantages of proactivity in target detection, sharp directivity of probe field and strong antielectromagnetic interference ability. Recently a new kind of small laser fuze adapted to small-caliber ammunitions is being actively developed. Designed the mathematic model of the laser echo waveform based on Gauss beam and deduced time domain of echo impulse power with varied sharps of target (such as plane target, circle target and mutant target). Echo impulse waveform of laser fuse with the noise interference, such as sunlight and raindrop, also has been studied based on the modeling. The test experiments show that the system can detect weak laser echoed wave, distinguish target and interferences signal by amplifying, modulating and processing the echoed waveform, and detect vertical test board (gray iron) at 5m far away with no more than 90mA current. The test results in High overload conditions indicates that the prototyping can work normally and steadily in the whole trajectory.
