摘要
针对软件化雷达视频信号的实时性问题进行了研究,给出了常规警戒雷达信号处理的仿真模型,对每个处理模块的运算复杂度进行了详细的分析,采用IPP和常规计算方法对每个处理模块的运算时间进行仿真研究,并给出了结论:在四核2.34G CPU的工控机上,采用IPP算法比采用常规算法计算速度要高1～2个数量级,在1 500μs内,回波采样点数在32 768个以内,脉压、MTI、求模和恒虚警等处理模块都可以满足实时性要求,16通道动目标检测(MTD)在2 000μs内,回波采样点数在8 192个以内,可以满足实时性要求。
The paper mainly focus on the research of software radar video signal＇s real-time problem.Firstly,paper introduces conventional guard radar＇s signal processing simulation model,then gives the detailed analysis on the every processing module＇s computing complexity,then simulates the every processing module computing time in using conventional and intel integrated performance primitives（IPP）algorithms.At last paper comes to conclusion：On four-core 2.34G CPU industrial control computer,using IPP algorithms are 10～100 times faster than using conventional algorithms.In 1500 μs,in 32768 radar echo samples,pulse compressing,moving target indicator（MTI）,magnitude and constant-false-alarm-rate（CFAR） can meet the demand of real-time.As far as 16-channels moving target detection（MTD）,it can meet the demand of real-time in 8192 radar echo samples in 2000 μs.
