Abstract

Electronic Warfare Support Systems (ESM/ELINT) receive, process, analyze and direction finding signals sent by radars. Direction Finding and determining the Direction of Arrival (DOA) is one of the most important radar parameters that plays an important role in the operations of processing, de-interleaving, Clustering, classification and location of radars. Various techniques are used to direction finding (DF) and estimate the angle of Arrival. Among the methods, amplitude comparison direction finding (ADF) is one of the most common techniques due to its high speed and low computational complexity. Multipath fading degrades the performance of Direction Finding systems. In hilly and suburban environments, the direction finding accur
