目前外辐射源雷达主要以接收辐射源的直达波信号为主,该方式提取的直达波信号信噪比高,利于后续目标信号检测和处理,但需要收发站通视,对直达波天线架高有要求,这极大地限制了该体制的应用。基于此,文中提出在沿海低海拔条件下,利用超视距侦察截获辐射源信号成为非合作探测的基准信号的思路,分析了其探测机理,和理论误差模型,并结合工程实际,提出了可实现的工程样机,分析了性能指标,给出了仿真结果。结果表明该思路可以应用在后续的工程实践上。

Currently external illuminator radar use chiefly direct-arrival-wave received. The SNR of direct-arrival-wave extracted by this mode is large. It is profitable to detection and process of target signal, but It is necessary that the receiving station and transmitting station are visual in-the-horizontal and the receiving antenna of direct-arrival-wave installed highly is required, this structure application is large limited. Because of it, the idea that the signal by receiving illuminator signal in-the-horizontal in the height above sea level along sea zone become standard signal of external illuminator detective is proposed, and the detective mechanization、theory error model is analyzed, and combine actual engineering, realizable engineering sample machine is provided, property quota is analyzed, simulation fruit is provided, result indicate that the structure may apply subsequent projects.
