Abstract

Method to reconstruct images with frequency diverse subarrays at millimeter-wave frequencies is presented. The imaging system consists of a set of transmit and receive subarrays each having unique, strongly frequency-dependent radiation pattern. Signal transmissions between different transmit and receive subarray pairs are recorded at multitude of frequencies and the image is solved from the set of these measurements. Target space is observed with each subarray pair and with the known subarray field patterns, the target locations are determined. Simulation study of the method has been conducted and the evaluation of the results proves that the method is viable and could be used for imaging purposes.
