Abstract

In this paper, we focus on several signal detection method and wavelet analysis method for radar echo signal detection. According to the characteristics of signal detection and modern signal processing theory, we have deduced and analyzed the principles of these algorithms in mathematics, which involves more profound knowledge such as higher-order statistics and wavelet, and of course. It is important that we perform wavelet analysis on the echo signals of the HF ground wave radar to remove the weak ionospheric clutter and the method performs well. Wavelet is an important mathematical application method in signal detection.
