Parallel Arithmetic of Two Dimension Arrived Angle and Polarize Parameter's Estimate

Two dimension arrived angle and polarization parameter's estimate arithmetic in radio wave have very important station in some applied domain. But it's needed large numbers of operations and a very long times, which can't suit for real-time need. Because of the real time needs of arithmetic, we analyzed, designed and implemented its parallel arithmetic. Then we tested the serial arithmetic, and tested the parallel arithmetic in four isomorphic computers, got higher acceleration ratio and efficiency. So it expresses the parallel arithmetic is effective.
