摘要
在电子战信号处理领域,快速有效的识别脉冲压缩雷达信号具有重要的现实意义。基于小波变换理论在信号去噪方面的理论,定义了均值小波能谱,进而提出了一种快速准确识别低信噪比线性调频信号调制参数的方法。通过计算机仿真,该方法对多组低信噪比线性调频信号的参数辨识误差均在5.5%以下,从而证明了该方法的有效性和实时性。
In the field of signal processing for electronic warfare,it is significant to recognize the pulse compression radar signal rapidly and effectively. Basing on the principle of wavelet transform in denoising,average wavelet spectra is defined and then a fast and accurate method for recognition of low SNR linear FM is proposed in this paper. The simulation of several low SNR linear FM show that the recognition errors are all below 5. 5% and thus demonstrate the effectiveness and real - time characteristic of this method.
