摘　　要：干涉仪测向分选一般是在DSP中完成,本文介绍了基于DSP的三种不同处理机制。基于多核的分发机制和并发机制都可提高处理的并行性,但并发机制存在多核同步,任务分配等问题,处理效率没有分发机制更高效。分发机制有效利用了干涉仪的本振频点遍历处理特点,流水并行提高了整体处理速度。Interferometer direction finding and sorting are generally completed in DSP.In this paper,three different processing mechanisms based on DSP are described.Both multi-core distribution and concurrency mechanisms can improve processing parallelism.However,the concurrency mechanism suffers from issues such as multi-core synchronization and task allocation,making it less efficient than the distribution mechanism in processing.The distribution mechanism effectively utilizes the local oscillator frequency point traversal processing characteristics of the interferometer,and pipeline parallel processing improves the overall processing speed.
