基于小波变换的频率捷变引信信号分析

Analysis of the Frequency Agile Fuze Signal by Using Wavelet Transfort

频率捷变引信作为一种新体制的引信,回波信号有其特点,文章在选取相应的参数后,利用小波变换(WT)对频率捷变引信的回波信号进行分析,揭示了此信号的时—频域特征,为引信的精确定距提供了依据。

As a new system radio fuze, the signal received by frequency agile fuze has own characteristics. In this paper, the proper parameters are chosen, the signal are analysed by using wavelet transfort, some features in time - frequency domains are found which provide some basis in theory to measure accurate distance.
