Abstract: In this paper, the signal processing system of the windshear radar was simulated, which mainly included echo signal simulation of microburst, echo signal simulation of ground clutter, clutter suppression, wind speed extraction and risk factor calculation. The simulation results showed that the Fast Fourier Transform (FFT) and Pulse Pair Processing (PPP) methods had similar wind speed estimation performance under general conditions, obtaining good wind speed estimations in the core microburst area. When the local clutter was very strong, the ground clutter filter might cause deviations in wind speed estimation. However, ground clutter filtering was unnecessary for the pattern recognition method, which could ensure the integrity of the meteorological signal echo.

Keywords: windshear detection; ground clutter suppression; PPP; pulse pair processing method; FFT; fast Fourier transform method.
