Abstract :
A fast calculation method of 2-dimensional MUSIC, which can estimate two parameters such as DOA and frequency, is proposed. In the proposed method, 2-dimensional search calculation is substituted with FFT (Fast Fourier Transformation) and convergent calculation. Simulation results showed the proposed method is approximately twenty times faster than the conventional method.
