摘要

针对目前常用的长时间积累方法存在的缺陷，提出了一种基于多核数字信号处理(DSP)并行系统的PSO并行跟踪算法，该算法大大降低了计算成本和复杂度，准确补偿了目标，提高了处理实时性。共进行了三次飞行试验。每次均采用传统的10ms累积法和并行粒子群跟踪法同时对目标进行跟踪。实验结果表明，并行粒子群跟踪算法具有较低的可计算复杂度和较好的实时性。

Design and implementation of long-time coherent integration algorithm based on Multi-Core DSP

Due to the defects of the long time accumulation method often used now, a new parallel PSO tracking algorithm based on Multi-core Digital Signal Processing (DSP) parallel system was proposed which greatly reduced the calculation cost and complexity, compensated the target accurately and enhanced the real-time processing. A total of three flights experiment was carried out. Every time both the conventional 10ms accumulation method and parallel PSO tracking method were adopted to track the target at the same time. The experiment results showed that the parallel PSO tracking algorithm was tracking the target with less computable complexity and more effective real-time performance.
