| Abstract: | The paper constructs a virtual array based on conjugate data rearrangement and develops a new spatial time frequency distribution by the Wigner Ville distribution between the actual array and the virtual array. Based on subspace projection and an L shaped array, a method to estimate 2D DOA of wideband chirp signals is presented. The theoretical analysis and simulation illustrate that the proposed algorithm is effective. |
