Joint diagonalization DOA matrix method

A novel joint diagonalization (DOA) matrix method is proposed to estimate the two-dimensional (2-D) DOAs of uncorrelated narrowband signals. The method constructs three subarrays by exploiting the special structure of the array, thereby obtaining the 2-D DOAs of the array based on joint diagonalization directly with neither peak search nor pair matching. The new method can handle sources with common 1-D angles. Simulation results show the effectiveness of the method.
