长基线时差定位体制的多站无源探测定位系统对采用窄波束发射的辐射源存在一定的难度,影响其实际使用.文中以多站无源探测定位装备的单个侦察站为基础,利用空频域信息实现对目标辐射源的单站无源定位.在保持现有系统硬件不变的基础上,设计了单多站一体化无源探测定位系统结构,讨论了系统实现的关键技术和解决途径,并通过仿真方法提出了单站无源定位对角度、角速度、多普勒频率参数测量的要求,这对改造现有的多站无源定位系统和扩展多站无源探测定位范围具有一定的参考意义和应用价值.仿真实验表明,单站无源定位系统对角度的测量精度要达到mrad量级,角速度的测量精度要达到mrad/s量级,多普勒频率变化率的测量精度要达到Hz/s量级.

It is difficult for multi-station passive detection and location system to locate the radiant point using narrow radiation beam if the system uses long baseline and time difference techniques.In this paper,single observer passive location is realized to locate target radiation point via spatial-frequency domain information based on a single station of multi-station passive detection and location equipment.An integration of single and multi-station system structure is designed under condition of presering th...
