摘要
利用新近研制的超高频频段多通道外辐射源雷达系统,在国内率先开展基于数字电视信号的移动平台外辐射源雷达实验研究.首先建立了单频网结构下移动平台接收信号模型.接着详细论述了利用扩展相消批处理算法与空时自适应处理联合抑制直达波和地杂波的方法.最后重点介绍了实验开展情况,包括系统配置、典型结果与分析.仿真和实测数据的处理结果证明了模型的正确性和所用方法抑制杂波的优越性,为该探测技术的发展提供了理论和实验基础.
The latest domestic experimental research of UHF passive radar on moving platform based on digital television signal using the newly-developed multi-channel passive radar system is conducted.Firstly,the receiving signal model in the single frequency network(SFN)is established.And then a clutter suppression method combined the improved extensive can cellation algorithmbatchs(ECA-B)and space-time adaptive processing(STAP)is discussed in details.Finally,the experimental progress is highlighted,involving system introduction,illustration and analysis of typical results.The results of simulation and measured data processing prove the validity of the model and the superiority of the clutter suppressing method,forming the theoretical and experimental basis for the further development of this detecting technology.
