| 摘 要： | 在激光脉冲相关检测系统中,针对窄带滤光片的非理想性以及并联探测单元之间的背景光干扰存在相关性的问题,提出了一种相关检测系统的改进方法.利用两路探测单元同时接收目标信号和背景光的混合信号,另两路视场完全相同的探测单元仅接收背景光,将它们的输出分别对应相减后再进行相关处理,从而抑制了各单元间相关的背景光干扰.采用Simul...

| Abstract: | For the problem that laser pulse correlation detector faces challenges of both imperfect narrow-band filter and dependency of background light interference received by parallel detectors,an improved method is proposed.Two of four parallel detectors are used for receiving target signal and background light,while the other two receive background light only.The correlation background light interference is restrained through subtracting background light from the mixed signal before correlation processing.Simula... |
