Abstract Abstract: Wind-profiling radar that has developed in recent years is wind remote sensing device and has the broad application prospect in meteorological science research and weather forecast. Based on Doppler principle, wind-profiling radar aims clear sky as a detection object and can get atmosphere wind field information continuously by making use of electromagnetic wave scattering by atmospheric turbulence. Since detection signal of wind-profiling radar is very weak, it will probably be noise submerged. Adopted band of boundary layer wind-profiling radar is L-band and it is affected very easily by various electromagnetic devices since there is much electronic equipment working in this band. This paper analyzes spectrum of received by boundary layer wind-profiling radar under various interference circumstance, summarizes spectrum type of various interferences and reviews influence of the various interferences for generation product of wind-profiling radar. We put forward comprehensive countermeasures in signal processing and data processing, etc. and verify actual effect.
