摘要
Abstract
In order to solve the shortage of computing ability in radar data process with increasing computation,two parallel process methods are proposed based on the analysis of radar data process.The first method,the loop operations in every step of data process are processed by multiple threads,which is fine-grained parallel; the second method,radar detecting airspace is divided into several parts by radial range based on the locality feature of radar data,the divided parts are processd by multiple tasks,which is coarse-grained papallel.The experiment result shows that,the performance of 4 threads finegrained parallel radar data process architecture is almost 3 times of serial data process,and the performance of 4 tasks coarse-grained parallel is nearly 5 times,which proves parallel process is effective in radar data process and tasks level coarsegrained parallel architecture is more suitable.关键词
