摘要:

针对复杂的战场电磁环境对无线电引信构成干扰后引发早炸、削弱击打效能的情况,对调频引信干扰威胁最大的扫频式干扰,提出一种基于小波包字典稀疏表示的调频目标识别方法。选取三层小波包熵特征作为原子构建稀疏字典,引信检波端输出信号在小波包稀疏字典进行稀疏分解,将稀疏表示系数进行稀疏重构,通过重构误差最小原则,确定引信目标信号的类别。调频无线电引信样机的实测数据进行实验验证,验证结果为目标识别准确率达到98.72%,干扰识别准确率达到97.94%。这表明了所提方法能够有效的对调频引信目标信号和几种典型扫频式干扰信号进行有效的识别。

Abstract:

Aiming at the situation that the complex battlefield electromagnetic environment jamming with the radio fuze, which causes early explosion and weakens the striking efficiency, a frequency modulation target recognition method based on sparse representation of wavelet packet dictionary is proposed for the sweep frequency jamming, which is the most threatening jamming to the frequency modulation fuze. The sparse dictionary is constructed by using the three-layer wavelet packet entropy feature as the atom. The output signal of the fuze detection end is sparsely decomposed in the wavelet packet sparse dictionary, and the sparse representation coefficient is sparsely reconstructed. The classification of the fuze target signal is determined by the principle of minimum reconstruction error. The experimental verification of the measured data of the frequency modulation radio fuze prototype shows that the accuracy of target recognition reaches 98.72%, and the accuracy of interference recognition reaches 97.94%. This shows that the proposed method can effectively recognize the target signal of frequency modulation fuze and several typical sweep frequency jamming signals.
