枪口火光探测系统研究
System Research Based on Muzzle Flame
摘要
Abstract
Focused on the problem of low sensitivity and low signal to noise ratio(SNR)in the detection system of muzzle flame,this paper mainly researches froe-end detection circuit of muzzle detection system which is based on PBS detector.The math?ematical model of the detector is established and through analyzing the voltage change ratio at front of the detector,the best match?ing resistance has obtained with the maximum voltage change ratio,which is improve the detection sensitivity and SNR of the sys?tem. The paper chooses the PBS detector and best matching resistance mathematical model is proved by detecting the flame of 12.7mm rifle.关键词
