某型导弹射手失误信号的时频分析研究

摘要

在某型导弹飞行训练中，射手失误后，对信号的处理不能准确得出失误发生的时间、失误的程度、失误的原因。针对这个问题，分析信号的特点，对几种典型的时频分析法进行比较，提出了用连续小波变换时频法分析射手失误时的信号。通过Matlab仿真实验证明，笔者提出的方法对射手失误信号的处理是有效的，能准确地确定失误的位置和程度。有助于查找失误的原因。%In the training of a certain missile, the signal processing of having a mistake for shooter can not get the time it happened, the reasons for failure, the extent of mistakes. Aiming at the problem, signal characteristic is analyzed and several important time-frequency analysis methods are compared and continuous wavelet transform to analyse the signal is put forward. The simulation shows that the mean which is used to process the signal is effective. It can find the location and extent of mistaking exactly and help to find the reasons of mistaking.
