在本文中，我们基于点响应的二维傅里叶变换的相位与其距离-时间历史之间的关系，对频域 SAR 处理进行了一般分析。 该论文演示了这如何为相干带模式处理器的设计提供适当的基础，没有几何或相位失真和伪影，并且没有过多的计算成本。 因此，本文与SAR数据的实时、精确处理具有高度相关性。 本文评论了该分析与模糊度估计和超长积分时间SAR数据处理的相关性。
In this paper we present a general analysis of frequency domain SAR processing based on the relationship between the phase of the two-dimensional Fourier transform of a point response to its range-time history. The paper demonstrates how this provides an appropriate basis for the design of a coherent strip-mode processor, free of geometric or phase distortion and artefacts, and without excessive computational cost. In consequence the paper is highly relevant to the real-time, precision, processing of SAR data. The paper comments on the relevance of the analysis to ambiguity estimation and the processing of very long integration time SAR data.
