摘要
在天幕靶数据采集系统中,弹形信号夹杂着各种噪声,难以反映其真实值,而且对单一弹形的处理也并不能得到弹形信号之间的关联性。本文基于卡尔曼滤波原理与方法,对连续弹形信号进行滤波处理,再通过相干检测,分析弹形之间的相干性。用Matlab对滤波信号与原始信号进行相干检测,并分析弹形信号之间的联系,证明该算法的有效性。最后通过实弹测试,实验结果表明,该算法提高了天幕靶数据采集系统的精度,并对靶场数据采集系统有着重要意义。
In the sky screen data acquisition system, the bullet - shaped signal mixed with all kinds of noise,it is diffi- cult to reflect the reality of the bomb - shaped signal, Deal with a single bullet - shaped shells signal also could not get the link among them. This paper based on Kalman filter principles and methods, after filtering the continuous bullet signal, then analysis the correlation between the bullet. With the tools of Matlab, deal with the filtered signal and the original signal, then find the coherence function, to confirm effectiveness of filtering and analyzing pulse bomb among them. Finally, the validity of the method is also confirmed through the live- fire testing,algorithm to improve the data acquisition and analysis the system of the sky test system has a range of great significance.
