Abstract


This paper addresses the problem of determining the Directions-of-Arrival (DOA’s) of narrow-band emitter signals impinging on a sparse sensor array. We assume that array incorporates several identical widely separated subarrays. A new TLS-ESPRIT-based DOA estimator is obtained for this class of sparse sensor arrays. The generalization of the TLS-ESPRIT that includes structure (row) weighting method is discussed. Simulation results are included to show the performance of proposed estimator.
