Abstract: How to continuously improve the detection capability of wind profiler radar is a problem facing researchers. The existing wind pro fi ler radar equipment and technical reserves are a low-cost and quick-acting scheme that use electromagnetic compatibility technology. By improving the grounding, shielding, fi ltering and wiring schemes, and controlling the time-sharing operation of the receiver and transmitter, the interference can be signi fi cantly suppressed, the noise can be reduced, the sensitivity of the receiver can be improved, and therefor detection capability of wind pro fi ler radar can be improved.
