Radar interferometry at millimeter-wave frequencies has the ability of topography measurement of different types of terrain, such as water surfaces and tree canopies. A Ka-band interferometric radar was mounted on an airborne platform, and flown over the Connecticut river region in western Massachusetts near Amherst on June 11, 2012. More than 20 Gigabytes of raw data was recorded. This dissertation outline presents the results of the data processing, which includes (1) the estimation and removal of the embedded high frequency phase error in the raw data; (2) the synthetic aperture processing; (3) the interferometric processing. The digital elevation model (DEM) has been generated based on an external DEM from MassGIS. The accuracy of the topography measurement can be affected by many factors, such as the de-correlation between channels and the residual phase error. This dissertation outline proposes to evaluate the accuracy of the topography measurement by quantifying each error source. Specifically, the performance of the phase error estimator and the Doppler centroid estimation will be analyzed, and an algorithm which estimates the attitudes of the airborne platform will be developed.
