摘要

我们表明，未来高分辨率SAR模式的性能将受到异常传播效应的限制，而不是受到平台测量误差、聚焦算法限制或RF波长的限制。这是通过计算由特定的大气温度分布引起的相历史畸变来建立的。仿真显示了这种相位畸变对SAR图像的影响。

Anomalous propagation limitations to high-resolution SAR performance

We show that the performance of future high-resolution SAR modes will be limited by anomalous propagation effects, rather than by platform measurement errors, or focusing algorithm limitations, or RF wavelength. This is established by calculating the phase history distortions that result from specified atmospheric temperature profiles. Simulations show the effects of such phase distortions upon SAR images.
