摘要：
The characteristics of airborne millimeter-wave Interferometric Synthetic Aperture Radar (InSAR) include unrestricted light, large surveying width, and high mapping precision. In recent years, with the continuous development and improvement of the technology of airborne millimeter-wave InSAR, it has gradually become a widely used mapping method. The core of the system design of a high-precision millimeter-wave InSAR system designed for small aircraft platforms comprises InSAR baseline configuration, multibaseline configuration, the external Digital Elevation Model (DEM), and InSAR processing flow. In this study, interferometric elevation measurements influenced by different baseline parameters of an airborne millimeter-wave InSAR system are analyzed. A design scheme of the millimeter-wave multi-baseline InSAR system based on integrated antenna pod is provided. Then, a time-domain imaging algorithm-based millimeter-wave multibaseline InSAR elevation measurement process is proposed. Finally, real measured data experiments are used to illustrate the feasibility and effectiveness of the proposed millimeter-wave multi-baseline InSAR system and the interference data processing method for large-scale mapping missions. © 2019 Institute of Electronics Chinese Academy of Sciences.
