Abstract: A new algorithm to estimate jointly the Direction-Of-Arrival (DOA) and range of near field sources is presented. Firstly, the whiten matrix is constructed by use of the second order statistics, and then the array steering matrix of near field sources is estimated by use of joint diagonalization of the array cumulant matrices, which exploits the structural information of the higher order statistics of the data received by the array. Thus the DOA and range can be estimated from the array steering vectors simultaneously. Compared with the higher-order ESPRIT method, the new algorithm can improve the efficiency of elements. In addition, it does not need any operation of parameters pairing. Its good performance is verified by computer simulation results.
