摘要: 弹载无源探测器由于自身高速运动,探测系统几何配置关系变化迅捷,卫星的选取直接影响系统探测能力,因此提出相应的卫星优选方法极为重要。针对该问题,以北斗卫星导航系统(BDS)卫星作为机会辐射源,给出了弹载无源探测器的分辨力要求;利用双站模糊函数和角分辨力公式推导出目标分辨力与探测系统几何配置间的定量关系;结合分辨力要求反推出对空间几何配置关系的约束条件,给出了相应的BDS卫星优选方法。仿真结果验证了该卫星优选方法的可行性和有效性。

Abstract: The geometric configuration relationship of detection system changes rapidly due to the high speed movement of missile-borne passive detector. The detection ability of the system highly relies on the selection of satellites. To solve this problem, BDS (BeiDou navigation satellite system) satellites are selected as opportunity illuminators, and the resolution of missile-borne passive detector is figured out. The quantitative relationship between the resolution of detector and the geometric configuration of detection system is deduced by using bistatic ambiguity function and angular resolution function. The constraint of the geometric configuration relationship is reversely derived depending on the resolution requirements. Optimization principle of BDS satellite selection is then concluded. The simulated results verify the feasibility and effectiveness of the proposed optimization principle of BDS satellites selection. Key
