摘要

卫星合成孔径雷达干涉测量（InSAR）作为一种可全天候、全天时工作的空间对地遥感观测技术，在地形重建、地表形变提取、以及地学参数反演等方面已得到广泛应用。作为传统InSAR技术的延伸，近年来SAR分谱干涉测量技术（如SAR距离向分谱干涉、方位向分谱干涉和TOPS模式Burst重叠区干涉）在干涉相位解缠、地表三维形变提取、以及电离层误差校正等方面展示了巨大的应用潜力。本文概述了星载SAR分谱干涉测量技术的发展现状，重点介绍了SAR分谱干涉测量原理和数据处理方法，系统分析了SAR分谱干涉在高精度地形测绘、大梯度地表形变观测、多维地表形变信息提取、以及InSAR电离层误差校正等方面的最新研究进展。此外，本文还讨论了利用SAR分谱干涉技术监测高精度地表形变的最优参数配置方案，并对SAR分谱干涉测量的发展趋势进行了展望。

Abstract

Interferometric synthetic aperture radar (InSAR)

as an all-weather and 24-hour operational spaceborne remote sensing technology

has been widely utilized in applications such as terrain reconstruction

surface deformation detection

and geophysical parameter inversion. As an extension of traditional InSAR technology

SAR split-spectrum interferometry techniques (including SAR range split-spectrum interferometry

azimuth split-spectrum interferometry

and TOPS mode burst overlap interferometry) have shown significant potential in fields such as interferometric phase unwrapping

three-dimensional surface deformation extraction

and ionospheric error correction in recent years. This study aims to provide a comprehensive overview of the development status of satellite-borne SAR split-spectrum interferometry techniques

with a particular emphasis on their principles and data processing methodologies. A total of 112 scientific papers published between 1992 and 2024

focusing specifically on the topic of split-spectrum interferometry

were reviewed. The review content was organized into four main parts: SAR sensors

current research progress in SAR split-spectrum interferometry

applications and advancements of SAR split-spectrum interferometry

and challenges and future perspectives of SAR split-spectrum interferometry. The paper offers a comprehensive summary and insights into the development of split-spectrum interferometry through analysis. First

this study summarizes the current SAR satellites

including commercial platforms. Then

it introduces the fundamental principles of SAR split-spectrum interferometry and systematically reviews its latest advancements in areas such as high-precision terrain mapping

surface deformation monitoring in regions with steep gradients

multidimensional surface deformation extraction

and ionospheric error correction within InSAR frameworks. Additionally

the study explores optimal parameter configuration schemes for high-precision surface deformation monitoring using SAR split-spectrum interferometry. Future trends in the development of this technology are also outlined in this paper. Continuous innovations in SAR technology enable the advancement of satellite-borne SAR systems toward broad bandwidths

multiangle observations

multifrequency capabilities

diverse polarizations

and satellite constellations. Techniques such as range split-spectrum interferometry and azimuth split-spectrum interferometry are expected to enhance accuracy in deformation measurements and ionospheric error correction

whereas burst overlap interferometry may significantly enhance the spatial coverage of deformation monitoring. Ultimately

these advancements are poised to establish a high-precision

multidimensional deformation monitoring system that integrates InSAR with SAR split-spectrum interferometry

thereby driving innovations in large-scale terrain mapping

geological hazard monitoring

and global environmental change assessments.
