Real-time Signal Processing System for Weather Radar

摘要

In this paper, a new signal processing system used for modern weather radar will be introduced. The system processing is used on dual_linear polarization Doppler weather radar. The conventional pulse weather radar only observes one parameter Z (Reflectivity factor), the data scale is more smaller than modern pulse Doppler radars and dual-polarization radar. Therefore, a new digital signal processing system is desired to realize the demands. This system is composed of four parts: HSP(Hardwired Signal Processor), Signal Interface, HSO(High Speed Operation Module) and Host Port Interface.
