The Direction of Arrival (DOA) methods has great applications in the field of wireless communication. The case may be to locate an illegal transmission or to identify the target in the battlefield. This conference article presents a new DOA method. The new method estimates DOAs by using Fuzzy logic system to classify the detected peaks in the spatial spectrum and identify the correct DOAs using an antenna array operating at 2050 MHz. The rest detected peaks discard as it is a false peaks. The new method reduces the computational complexity of super-resolution algorithms such as Incoherent Multiple Signal Classification (Incoherent-MUSIC) and Test of Orthogonality of Project Subspaces (TOPS). The performance of the current method is compared to that of the IMUSIC and TOPS algorithms.
