Robust Phase Bias Estimation Method for Azimuth Multi-Channel HRWS SAR System Based on Maximum Modified Kurtosis

方位多信道合成孔径雷达系统在实际工作中不可避免地存在通道相位偏差。为了准确估计相位偏差，本文提出了一种基于最大修正峰度的通道相位偏差估计方法。通过分析多通道合成孔径雷达的回波特性，本文构建了重构多普勒频谱的目标优化函数，从而准确估计通道相位偏差。仿真实验和真实数据处理验证了所提方法的有效性和鲁棒性，该方法不受场景限制，在低信噪比下具有良好的估计性能。[pdf, SCI, IF=2.8997, CAS-G4, JCR-Q2]
