Joint DoA-range-Doppler tracking of moving targets based on compressive sensing

In this paper, the tracking of moving targets using a stepped frequency linear antenna array is addressed through the compressive sensing (CS) framework. Multiple targets are resolved in the three-dimensional directions of arrival (DoA)-range-Doppler space for each time instant. The Orthogonal Matching Pursuit (OMP) algorithm is utilized to reconstruct the target space using measurements at a small number of randomly selected frequencies. The performance of the proposed approach is evaluated through simulation result in terms of accuracy and computational complexity.
