Algorithm for resolving phase ambiguity in estimating parameters of ground moving objects

The scheme and main characteristics of an aerospace SAR-interferometer for remote sensing of the Earth's surface operating in telescopic mode are considered. An algorithm for resolving phase ambiguity when estimating radial and tangential velocities of ground moving objects is proposed. The effectiveness of this method was tested by simulation modeling in the Matlab environment. The possibility of using the proposed ambiguity resolution method conjunction with multidimensional difference-phase processing for estimating parameters of moving objects is demonstrated. Experimental results on the detection and velocity estimation of moving objects using interferometric processing and algorithm for resolving phase ambiguity for radio holograms recorded on an aviation platform and received through two spatial channels.
