摘要

本文研究了天线方向图变细对多输入多输出雷达图像的影响。首先，MIMO阵列输出幅值不一致，导致近场条件下图像离焦;其次，它会导致校准图像的测量散射强度损失。为了减小这些影响，提出了一种天线方向图补偿技术。仿真结果验证了所提技术的性能。

Antenna pattern compensation technique for near field MIMO radar imaging

In this paper, effects of antenna pattern tapering on multiple-input multiple-output (MIMO) radar image are studied. First, it brings about amplitude inconsistency of MIMO array output, which results in imagery defocusing under near-field condition. Second, it leads to the loss of measured scattering intensity for calibrated images. An antenna pattern compensation technique is proposed for reducing these impacts. Simulation results are presented to validate the performances of the proposed technique.
