摘　　要：考虑到引信点火脉冲输出的电信号波形具有极短的上升时间和较长的衰落时间特征,对其进行采样时,定时精度往往会存在较大误差。该文提出基于恒比定时甄别的定时点优化策略,其将原始信号通过FIR低通滤波处理,并对采样点进行波形重构,之后进行寻峰并在线消除基线漂移,最后根据重构后波形,进行衰减、延迟与叠加,最终获得恒比定时点。测试结果表明,所提方法将定时点的测试精度提高40%,具有较好的性能。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.
