Kurzbeschreibung (Abstract)
Direction-of-arrival (DOA) estimation in partly calibrated array composed of multiple fully calibrated subarrays is considered. The location of the sensors in the subarrays are assumed to be arbitrary, i.e., no specific subarray geometry is assumed. Using array interpolation, we extend the previously proposed decentralized ESPRIT algorithm (d-ESPRIT), originally designed for shift-invariance array geometries, to arbitrary array geometries. In our proposed algorithm, the array interpolation is carried out locally at the subarrays, thus, communication between the subarrays is required for DOA estimation but not for interpolation. Simulation results demonstrate that our proposed algorithm achieves better performance than the conventional ESPRIT algorithm in perturbed shift-invariance arrays.
