Abstract: The present disclosure provides a system and a method for generating a radar image of a scene. The method comprises receiving radar measurements of a scene collected from a set of antennas, wherein the set of antennas are under uncertainties caused by one or a combination of position ambiguities and clock ambiguities of each of the antennas. The method further comprises generating the radar image of the scene by solving a sparse recovery problem. The sparse recovery problem determines, until a termination condition is met, a set of image shifts of the radar image corresponding to different uncertainties of the antennas and updates an estimate of the radar image, based on the determined set of image shifts of the radar image. The sparse recovery problem is solved with a neural network denoiser that denoises a filtering of the estimate of the radar image.

Abstract: Systems and methods for tracking targets by a network of radar sensors each monitoring targets in a portion of an extended range. Each radar sensor characterizes and identify the detected targets and communicates metadata with neighboring sensors such that the identified targets may be uniquely identified and continuously tracked as they move between different portions of the extended monitored region. In a retail environment, customer behavior may be monitored with a customer journey generated indicating a path taken by each identified customer.
