| 摘 要： | 在均匀分布和非均匀分布两种情况下,采用二维MUSIC算法研究了星载稀布L阵列的地面辐射源测向精度。对地面辐射源方位估计、小角度辐射源分辨率,以及测向精度的分析和仿真结果表明,星载L型阵列能实现对地面辐射源的高精度二维测向。在相同条件下,非均匀阵的测向性能明显优于均匀阵。

| Abstract: | The precision of direction finding for the space-borne sparse L-arrays those were symmetrical and asymmetrical distributed was studied using 2-diamension MUSIC algorithm under the condition in this paper.The analysis and simulation results of the direction estimation of the ground emitter signals,the resolution of the emitter signals with small azimuth angle,and the precision of the direction finding were showed that the high precision direction finding for the ground emitter signals could be realized by the space-borne sparse L-array.The asymmetrical array had much higher accuracy than symmetrical one. |
