2-D DOA Estimation of Wideband LFM Signals for Arbitrary Planar Array

摘要：

A novel 2-D DOA estimation algorithm of multiple wideband LFM signals is proposed which can be applied to arbitrary planar array. Based on the energy concentration property of LFM signal in fractional Fourier domain, a new array data model is constructed. By using the generalized rotation matrix defined between subarrays, the conventional ESPRIT algorithm is revised, and hence achieves the 2-D DOA estimation for arbitrary planar array. The simulation results verified the efficiency of the algorithm.
