Abstract

In this paper, a new direction-of-arrival (DOA) estimation technique applicable to partly-calibrated arrays (PCAs) composed of arbitrary subarrays with unknown subarray displacements is developed. The new method is not restricted to any specific array geometry and allows joint estimation of the DOAs and calibration of the entire sensor array. Computer simulations show that the proposed approach substantially outperforms the known DOA estimation methods applicable to such PCAs.
