多雷达组网抗干扰中的若干关键难题

Some Key Problems in Jamming Suppression of Muti-radar Network

雷达干扰因其实现了对雷达时、空、频等多域覆盖,且具有对雷达信号变化快速跟随能力,使单部雷达在干扰条件下靠自身抗干扰技术达到的作战效能被大大压缩。在体系化作战思维牵引下,利用多雷达组网工作是复杂干扰条件下提高雷达探测能力的有效途径之一,基于对雷达干扰的抗干扰技术途径分析,以多雷达组网探测为基础,分析了双/多雷达控制、状态、信息互联互通关系,重点提出了指挥控制关系、时空同步设计、信息互联等设计方法。同时参考开放式射频系统架构,提出了可动态配置的资源调度框架和流程,为多雷达组网在干扰条件下工作性能提升提供支撑。

The radar jamming achieves multi-domain coverage of radar time,space and frequency,and has the ability to quickly follow the radar signal changes,so that the combat effectiveness of single radar under the condition of jamming is greatly compressed.Under the guidance of systematic operational thinking,using multi-radar networking is one of the effective ways to improve radar detection capability under complex jamming conditions.In this paper,based on the analysis of the anti-jamming technology of the radar interference,based on the multi-radar network detection,the relationship between dual/multi-radar control,state and information interconnection is analyzed,and the design methods such as command and control relationship,spatio-temporal synchronous design and information interconnection are put forward.At the same time,based on the open RF system architecture,a dynamic configurable resource scheduling framework and process are proposed to support the performance improvement of multi-radar networking under the condition of interference.
