摘要

根据发射频率和信号带宽的不同，天基合成孔径雷达可能会受到小尺度结构电离扰动的影响。本文考虑了闪烁(振幅和相位变化)对窄带SAR的影响，该SAR采用相位梯度自动对焦(PGA)方法，试图补偿合成孔径上相位误差的影响。

The effect of ionospheric scintillation on phase gradient autofocus processing of synthetic aperture radar

Depending on the transmission frequency and signal bandwidth, space based synthetic aperture radar (SAR) may be impacted by disturbances caused by small-scale structured ionization. This paper considers the effects of scintillation (variations in amplitude and phase) on a narrow band SAR that utilizes the phase-gradient autofocus (PGA) method that attempts to compensate for the effects of phase errors across the synthetic aperture.
