Method of Eliminating Noise from Ultra-wideband Radars Based on Wavelet Decomposition

为提高超宽带雷达信号的信噪比,分析了运用小波变换的分解与重构理论来实现超宽带雷达信号去噪的原理,并进行了仿真,结果表明,这种方法具有较好的去噪能力,去噪效果与目标信号及干扰信号的特性有关。

The principle of applying the decomposition and reconstruction theory of wavelet transform to eliminating the noise from UWB radar signal is analyzed, and the simulation is carried out. The result shows that this method is better in noise elimination. The effectiveness of this method is related to the characteristics of the target signal and jamming signal.
