摘要
信号脉内特征提取技术是雷达对抗系统分选、识别截获信号的关键技术。提出了一种首先用小波分析对脉内频率编码信号进行去噪,在此基础上再利用小波脊线法提取脉内特征的方法。计算机仿真验证了算法的有效性,具有一定的应用价值。
Extracting of radar in-pulse characteristics is an important technology to sort and recognize intercept signal from the radar countermeasure systems. The in-pulse frequency-coded signal is denoised based on wavelet analysis firstly, and then the wavelet-ridge is used to extract the in-pulse characteristics. Computer simulation proves that the effective algorithm has a referenced value.
