基于恒比定时甄别的引信测试系统定时点优化方法
摘要
Abstract
As regards the characteristic of the fuze ignition pulse output electrical signal waveform,which has an extremely short rise time and a relatively long decay time,there is often a significant error in timing accuracy when sampling it.An optimized timing point strategy based on constant ratio timing discrimination is proposed.This strategy processes the original signal through FIR low-pass filtering,reconstructs the waveform for the sampling points,performs peak detection and online elimination of baseline drift,and finally,based on the reconstructed waveform,carries out attenuation,delay,and superposition to ultimately obtain the constant ratio timing point.Test results indicate that the proposed method has improved the timing point test accuracy by 40%,demonstrating good performance.关键词
