对地雷声引信目标识别技术进行了研究,提出利用小波变换后声信号在不同尺度的能量值作为目标的特征矢量,并采用均方加权距离分类器来识别坦克和直升机。检验结果表明,该方法提取的特征稳定,并且该技术具有高的识别率。
The target recognition technology of mine acoustic fuze was studied. The eigenvector of the acoustic signal at different scales after wavelet transform was proposed. The mean square weighted distance classifier was used to identify the tanks and helicopters. The test results show that the feature extracted by the method is stable, and the technique has high recognition rate.
