摘要

由于内存大小和计算时间的限制，传统的高分辨率(HR)方法在处理大型SAR图像时无法实现。本文从自回归(AR)光谱分析中衍生出一种新的HR光谱分析方法，称为“图像空间”，用于大图像SAR处理。仿真和实际数据处理结果表明，该方法不仅提高了分辨率，而且对杂波具有“良好”的处理性能。

High resolution SAR image analysis by new autoregressive algorithm in image space

Classical high resolution (HR) methods become unrealizable when applied to large SAR images, due to memory size and computational time requirements. In this paper, a new HR spectral analysis method, called "image space", derived from autoregressive (AR) spectral analysis, is proposed for large-image SAR processing. Simulations and real data processing results are provided, and demonstrate resolution improvement as well as "good" behavior on clutter.
