Abstract: A novel algorithm based on a T-shaped array for location of near-field source is presented.Under the far-field assumption of the actual near-field, equations for the bearings of far-field and the range and bearing of the near-field source are derived from two horizontal subarrays.The range and bearing of the near-field are obtained, and the bearing of another subarray determined.The azimuth and elevation of the near-field source can be determined from two bearings. The location of the near-field can then be estimated.More accurate results can be obtained by a local search.Simulation results show that the algorithm is accurate, effective and suitable for real-time applications.
