摘要

针对多层侵彻如何计算介质层数的问题,提出了一种全时态相对波峰检测算法。该算法主要以时间信息作为层数识别的依据,利用波峰顶点与其之前、之后的数据点差值的极性来初步识别波峰个数,再基于脉宽和峰峰间隔时间信息对波峰计数值进行进一步确认,以提高侵彻层数的计数正确性。经过仿真及靶场试验,该算法对数据处理可行、正确。该算法与现有的绝对阈值比较方法相比,并不完全依赖峰值,充分利用了信号所含有的时间和幅值信息,为侵彻层数计数算法提供了一种新的设计思想。

Abstract

A relative wave crest detecting algorithm base on all the tenses is proposed aiming at how to detect the number of medium layer on multilayer penetration. The algorithm mainly uses time information as a basis for the layer number recognition, then utilizes the polarity of the difference between the wave peak apex and the data points before and after it to preliminary identify the number of the wave peak, then bases on pulse width and fengfeng interval information for number of peaks for further confirmation in order to improve the correction of recognition the number of medium layer. The algorithm is feasible and correct in data processing through simulation and shooting range test. The algorithm provides a new design thought for the penetration layer recognition, does not rely solely on peak, makes full use of time and amplitude information of the signal comparing with the existing absolute threshold comparison method.
