针对令人关注的减小单星无源定位误差问题,提出了按最小二乘准则将单星测量的辐射源到达频率和相位差进行组合定位的方法,给出了这种定位方法的误差表达式.在对计算机仿真数据与按理论公式计算的结果分析和比较后,提供了定位误差分布等值线和组合定位误差减小系数等值线分布图.理论分析和仿真实验表明,组合定位的误差比同样条件下测量单一参数定位的误差小.

According to reducing location error, the emitter location from the combined set of frequency and phase difference measurements by a single satellite is presented. The analytic expression of location error of the method is also deduced. Some results of the Monte-Carlo experiments are given to confirm the theoretical conclusions, then the location error contours and error decrease efficient contours are shown. The analysis and simulation demonstrate that the location error is reduced by the proposed approach.
