摘要

近年来,多通道干涉SAR (InSAR)技术已被证明是通过解开干涉相位来重建数字高程模型(DEM)的有效方法。通常采用多基线或多频配置。本文讨论了在地面(GB-SAR)配置下联合利用多基线和多频率方法进行SAR干涉测量的可能性。利用Cramer-Rao下界(CRLB)和误差下界(ELB)对可实现的性能进行了分析。

Multi-frequency and multi-baseline ground based SAR for environmental monitoring
In the recent years, multi-channel Interferometric SAR (InSAR) techniques have proved to be effective in reconstructing the Digital Elevation Model (DEM) by unwrapping the interferometric phase. Commonly, multi-baseline or multi-frequency configurations are adopted for this aim. In this paper, the possibility of jointly exploiting multi-baseline and multi-frequency approaches for SAR interferometry in Ground Based (GB-SAR) configuration is addresses. An analysis of the achievable performances has been carried out, by exploiting both Cramer-Rao Lower Bounds (CRLB) and Error Lower Bounds (ELB).
