Paper Abstract

Interferometric Synthetic Aperture Radar (IFSAR) uses the phase difference between two SAR images acquired at different positions to infer ground topography. Conventional IFSAR technique is based on wideband transmitted waveforms. As a result, the interferometric phase forms an iso-Doppler surface containing the height information. In this work, we present a novel interferometric SAR technique using ultra-narrowband continuous waveforms to infer ground topography. Due to high Doppler resolution of the transmitted waveforms, we refer to this technique as the Doppler-IFSAR. We form SAR images by backprojecting onto iso-Doppler contours. We present the interferometric phase model for Doppler-IFSAR and outline the relationship between the height and interferometric phase.
