Abstract: Using cluster environment of shared memory multiprocessors, this paper studies parallel computing method processed by several high frequency real-time weather radars data. It presents two-stage parallel method which include a coarse grained message passing interface distributed memory and fine grained OpenMP shared memory hybrid programming, according to the single weather radar calculation characteristics and several radars mix processing method. Experimental results show that this method makes system radar data processing speed greatly enhanced.

Key words: weather radar, data processing, speed-up ratio
