Abstract

The super-resolution direction finding for wideband signals usually requires preliminary 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 Direction Of Arrival (DOA) method for wideband signals without preliminary DOA estimation, focusing matrices are formed on transformation to the signal subspace of every frequency, the covariance matrix of the individually measured frequencies is gained, then method for narrowband signals was used to estimate the DOA. The algorithm decreases the computation and it is easy to implement, wherever, it can be adapted to an arbitrary plane array, computer simulations proved the effective performance of the method.
