PARALLEL COMPUTING RESEARCH ON CLUTTER MODELING AND COMPUTER SIMULATION OF PULSE-DOPPLER FUZE
Clutter has a significant impact on the performance of airborne pulse-Doppler radars and hence is an important component of any radar model. The calculation of clutter of fuse essentially involves identifying the regions of the earths surface, which contribute clutter, and dividing these regions into sufficiently small elements according to the range resolution. The radar range equation may then be applied to the elemental area, clutter return accumulated in the end. For this method computation time is essentially proportional to input parameters such as the platform altitude and the pulse repetition frequency (PRF). Because of the very high PRF of fuse in contrast with normal airborne radar, it takes such a long time to model the clutter that the simulation cannot meet the efficient demand in practice. A parallel algorithm of coarse granularity was proposed and by solving the problems of load imbalance,communication consumption and data storage, we achieve the simulation and reduce the computation time significantly.
