Direction of Arrival (DOA) estimation methods are useful in Sonar, Radar and Advanced Satellite and Cellular Communication systems.DOA estimation addresses the problem of locating sources which are radiating ene rgy that is received by an array of sensors with known spati al positions. It was the desire to locate and track en emy aircraft using radar that initiated the concept of sensor array processing as a sub-discipline of electrical engine ering in the 1940s. The problem of direction finding or direction-ofarrival (DOA) estimation has become important in many other fields besides radar, for example, acoustic s ignals received by an array of hydrophones are used in und erwater applications to detect and locate submarines and su rface vessels. The wide range of applications for source localization has induced a correspondingly large am ount of research and refinement of techniques for estimatin g source locations. Over the years, these array processing t echniques have become more essential for battlefield and situ ational awareness. This paper studies the concept of direct ion of arrival estimation and the sparse techniques.
