侵彻层数全时态相对波峰检测方法研究

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。%A relative wave crest detecting algorithm based on all tenses was proposed to detect the number of medium layers of multilayer penetration.With the algorithm,the time information was taken as a basis for the layer number recognition,the polarity of the difference between a wave peak apex and data points before and after the apex was used to preliminarily identify the number of the wave peak,then based on pulse width and peak-peak time interval information,the number of peaks was further determined to improve the correctness of recognizing the number of medium layers.The algorithm was feasible and correct in data processing through simulations and shooting field tests.The algorithm provided a new design thought for penetration layers recognition.It was shown that the proposed method does not rely solely on peaks,it makes full use of time and amplitude information of signals comparing with the existing absolute threshold comparison method.
