摘　　要：雷达信号处理(RSP)系统的实时性一直是系统设计者需要重点考虑的内容之一。为提高雷达系统的实时性,本文提出了一种基于多模式雷达的RSP任务模型,并根据DP-Wrap算法和流水处理的思想提出了一种高效的任务调度算法。研究了在本模型下影响系统最小处理时间的因素,给出了系统最小处理时间的精确表达式,并在此基础上进行数值仿真,给出了根据RSP任务选择处理器个数的依据。Property of real-time for Radar Signal Processing（RSP） systems is very important to system designers. In this paper, a task model for RSP tasks based on multi-mode radar systems is proposed. Then the task scheduling algorithm based on DP-Wrap algorithm and pipelined processing is introduced with high performance. The accurate expression of minimum processing time of RSP tasks is given by the analysis of factors which influence the minimum processing time. The numerical simulation is performed to help to decide the number of processors corresponding to the RSP tasks.
