摘要
在分析外辐射源系统的模型和特点的基础上,针对外辐射源雷达直达波信号极易被遮挡而且不能满足系统对直达波信号信噪比要求这一难题,提出了一种基于分布式参考的外辐射源雷达探测系统,并构建了试验系统进行验证。试验结果表明:参考截获站转发的直达波信号满足系统直达波自适应对消和长时相关积累的要求,分布式参考站对进一步提升外辐射源探测系统的部署的灵活性具有重要意义。
On the basis of the analysis of the models and characteristics of the passive Radar system, for problem of the direct signals easy to be blocked and can’t meet the SNR requirements, in this paper, a passive Radar system based on distributed reference is proposed, tested and verified. The experimental results show that the direct signals forwarded by the reference interception station satisfy the requirements of adaptive cancellation and long-time integration. Distributed reference stations are important to further increase the flexibility of deployment of passive Radar system.
