| 摘 要： | 针对卫星无源定位系统对辐射源高精度定位的要求,以及日益复杂的电磁环境下时频重叠信号测向定位的难题,提出了单星阵列信号处理测向的方法,并对干涉仪和阵列信号处理测向的性能进行了理论分析和仿真比较,结果显示阵列信号处理测向比相位干涉仪具有更高的精度,在存在模型误差的情况下,基于盲源分离的测向算法比经典子空间投影测向算法具有更高的分辨力。

| Abstract: | To meet the requirements of high-precision emitter localization and several time-frequency overlap signals position in complex electromagnetic environment by single satellites, the methods of direction finding（DF） applying array signal are proposed. Theoretical analysis and simulation comparison for the performance of the interferometer and array signal processing DF show the latter has higher precision. In the case of model error, blind source separation DF algorithm possesses higher resolution rate compared with the classic subspace projection DF algorithm. |
