Abstract：This paper discusses the problem of estimating the spatial signature of signals under the gains and phases of sensors unknown with a uniform linear array (ULA). It is utilized the redundant structure of the ULA and subspace-based ESPRIT-like algorithm is introduced to obtain, a closed form solution for the spatial signature of signals, and the gains and phases of sensors is presented. The major advantage of the proposed ESPRIT-like algorithm is its low computational burden compared with the other iterative methods and its robustness Compared with ESPRIT algorithm. Numerical simulation is presented to test the validity and the performance of this algorithm.
