Fixing the spectrum width of the weatherecho signals, we change theirs mean Doppler frequency and filter them using regression filter. After filtering, we analyze the attenuation of them.
The analysis of the virtual echo such as three -body scatter spike echo, the secondary echo, the side -lobe echo is given echo based on observational re cords of severe convectional weather in 2003.
根据2003年几次强对流天气的观测资料，对其中三体散射长钉、二次回波旁瓣回波等虚假回波进行了分析。

Tests indicate that this scheme is one of the effective ways to solve the problems of storage and long-distance transmission of weather radar echo images.
