摘要
为了准确识别雷达回波信号中的目标信号,本文将小波变换引入到雷达回波信号处理,对回波信号进行分解、重构以及滤波器设计,去除雷达信号中的噪声,采用MATLAB软件进行系统仿真,结果表明,采用小波变换mallat算法对探地雷达回波信号进行目标识别具有较好的时频分辨率,且可抑制杂波,去除噪声,能很好的识别目标信号,具有很好的应用前景。
In order to accurately identify the the target signal of the radar echo signal, this article will introduce the radar echo wavelet transform signal processing on the echo signal decomposition and reconstruction, as well as design filter to remove the noise in the radar signal, using matlab software simulation results show that using wavelet transform with Mallat algorithm of the radar echo signal for target recognition have good time-frequency resolution, and can suppress the clutter, remove noise.it will be a very good mathod to identified the radar target signal,and has good application prospects.
