侵彻混凝土靶板层数快速算法
Fast Algorithm Research of Penetration Concrete Target Layers
摘要
Abstract
When the projectile penetrate concrete, in order to accurately control the initiation time to maximize the power of the warhead, to get the information of the number of layers of the penetration of concrete targets from measurement data a fast analytical processing timely is very important. This paper is proposed that the combination of lifting wavelet and median filter to pretreat the acceleration signal is used. Firstly, use lifting wavelet transform to separate the low-frequency components of the signal. Secondly,median filtering technology to filte out the mixed pulse and vibration interference are adopted. Calculating the short-term energy after pretreat signal, highlighting the strength of the contrast signal after square processing, weakening the effects of noise ,then threshold method to detect signal and obtain penetrating concrete target layers information quickly are adopted.关键词
