The super-resolution direction finding for wideband signals usually requires preliminary direction of arrival(DOA) estimation, whether it is accurate or not will play an important part to the final result. In order to avoid the process, paper proposed a method of founding focusing matrix for two-dimensional wideband signals without preliminary DOA estimation, it is founded on Robust coherent signal subspace method (R-CSSM), the results achieved has a preferable robustness and higher precise than conventional Rotational signal subspace(RSS) method, wherever, there are no special requirements for the array manifold, computer simulations proved the effective performance of the method.
