为应对以民用无人机为代表的低小慢目标“黑飞”“滥飞”所带来的低空安全威胁以及巡航导弹、战术导弹所带来的低空军事威胁,文中引入数字波束合成技术,设计并实现了一种面向低空预警雷达的信号处理控制平台,该平台具有实时性强、运算量大、传输速率高等特点。通过选用高速光纤传输与串行总线VPX技术,同时采用高性能模数转换器、超大规模现场可编程门阵列及高速专用数字信号处理芯片,实现了此平台的硬件架构设计,并在此平台上实现了一种基于数据流驱动的软件信号处理方案。得益于灵活的系统架构和丰富的硬件资源,该信号处理控制平台可以适应新技术的快速应用,便于低空预警雷达功能的升级扩展及性能的进一步提升,有效应对低空威胁。

In order to deal with the low altitude security threats brought by “black flight”and “indiscriminate flight”of low, small and slow targets represented by civilian unmanned aerial vehicles and military threats brought by tactical missile and cruise missiles, the digital beam forming technology is introduced, and a signal processing control platform for low altitude early warning radar is designed and implemented. The platform has the characteristics of strong real-time performance, large computation and high transmission rate. By choosing high-speed optical fiber transmission and serial bus VPX technology, and adopting high performance analog digital converter, super-large field programmable gate array and special high-speed digital signal processing chip, the hardware architecture design of the platform is realized, and a software signal processing scheme based on data stream driven is realized on the platform. Thanks to the flexible system architecture and abundant hardware resources, this signal processing control platform can adapt to the rapid application of new technologies, facilitate the upgrading and expansion of low altitude early warning radar functions, further improve its performance, and effectively respond to low-altitude threats.
