This paper presents a modified version of the method of direction estimation (MODE) that can estimate a greater number of sources than the original MODE. It is well-known that M-element arrays can basically estimate up to (M-1) direction of arrivals (DOAs), whereas MODE can only estimate up to M/2 DOAs because of its error-sensitive computation procedure. We propose a modified version of MODE that can estimate up to (M-1) DOAs. The performance of the proposed method was evaluated through computer simulation.
