摘要
Abstract
A distributed real-time processing system based on a multi-processor cluster is designed to address the storage bottleneck and processing-delay problem in high-resolution and wide-swath airborne SAR imaging.This system employs a star topology network based on serial rapid IO(SRIO)high-speed interconnection to mini-mize inter-processor communication overhead.By implementing range segmentation and load-balancing strate-gies,this system optimizes task allocation mechanisms,reduces remote operations and leverages the advantages of multi-node collaboration processing to significantly decrease memory requirements and processing latency.The test results verifies the feasibility and effectiveness of the SAR real-time processing system.关键词
