摘要
针对雷达信号处理带宽不足问题,基于国产高性能CPU设计信号处理平台。首先,基于国产高性能920模组设计硬件板卡并构建硬件测试平台;其次,根据固件、操作系统、中间件和编译软件搭建软件开发环境;接着,利用矢量、信号和图像处理函数库(VSIPL)软件编写规范设计信号处理应用软件;最后,基于雷达波形数据测试信号处理平台处理时效性。结果表明,在处理点数较大时,采用改进VSIPL中间件进行OpenMP多线程信号处理效果较好,可大幅缩减信号处理时间,具有一定的工程应用价值。
Aiming at the problem of insufficient bandwidth of radar signal processing,a signal processing platform is designed based on domestic high-performance CPU.Firstly,the hardware board is designed and the hardware test platform is built based on the domestic high-performance 920 module.Secondly,software development environment is built according to firmware,operating system,middleware and compiler software;Next,the specification is written and the signal processing application software is designed by using Vector Signal Image Processing Library(VSIPL)software;Finally,the processing timeliness of signal processing platform is tested based on radar waveform data.The results show that when the number of processing points is large,the improved VSIPL middleware is used for OpenMP multi-thread signal processing,which can greatly reduce the signal processing time,and has certain engineering application value.
