摘要

频变阵列多输入多输出雷达由于其波束距离相关，具有抑制主瓣干扰的巨大潜力。然而，对干扰抑制性能，输出信噪比的定量研究仍然不完整，特别是目标和干扰机空间位置的影响。本文提出了一个度量参数来表示FDA-MIMO雷达对传统MIMO雷达干扰抑制性能的增强，解释了目标和主瓣干扰器之间的方位角差异导致的性能下降。数值结果证实了理论分析，论证了空间位置对FDA-MIMO雷达性能提升的影响，给出了FDA-MIMO雷达抑制主瓣干扰的边界条件。

Effects of Spatial Position on Mainlobe Interference Suppression Performance of FDA-MIMO Radar

Frequency diverse array multiple-input multiple-output (FDA-MIMO) radar has significant potential for mainlobe interference suppression due to its range-dependent beam. However, the quantitative study of interference suppression performance, output signal-to-interference-plus-noise ratio, is still incomplete, especially the effect of spatial positions of the target and jammer. This article proposes a metric parameter to denote the performance enhancement of interference suppression for FDA-MIMO radar over the conventional MIMO radar, explaining the performance degradation caused by the azimuth difference between the target and mainlobe jammer. Numerical results confirm the theoretical analysis and demonstrate the effect of spatial position on the performance improvement for FDA-MIMO radar, presenting the boundary conditions of the mainlobe interference suppression for FDA-MIMO radar.
