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.
