摘　　要：多波束接收体制的相控阵雷达方位宽开且环境信号复杂密集,导致数据处理分机接收的脉冲流数据量大,复杂度高,处理速度缓慢。在多CPU架构的硬件环境下,对数据处理进行了一系列优化设计以完成高效处理,包括接收、存储与处理多任务并行处理;多CPU资源分析优化分配;根据耗时进行算法优化设计等方法。试验结果表明该方法有助于解决目标信息饱和条件下的目标增批、丢批率高等问题。The phased array radar with the multi-beam receiving system has wide azimuth and complex and dense environmental signals,resulting in a large amount of complex data from the data processing unit and slow processing speed.In the hardware environment of the multi-CPU architecture,data processing is optimized to achieve highly efficient processing,including multi-task parallel processing of receiving,storage and processing,multi-CPU resource analysis and optimization allocation,and algorithm optimization design based on time consumption.The test results indicate that the method can solve the problem of an increase in the number of targets and high loss rate under the condition of target information saturation.
