Abstract

The Danish Center for Remote Sensing (DCRS) has augmented its dual-frequency polarimetric synthetic aperture radar system (EMISAR) with single pass across-track interferometric (XTI) modes. This paper describes the system configuration, specifications and the operating modes. Analysis of data acquired in 1995 indicates that height resolutions better than one meter should be attainable at least in areas with benign topography where overlay shadows and phase unwrapping errors are minimal. Calibration procedures applied to correct for multipath and limited channel isolation are discussed
