摘要：Wireless sensor network systems have become revolutionize in recent years. Acoustic source Direction Of Arrival(DOA) is one of the essential phenomenon in many applications. Acoustic sensor network can provide a way to simulatenous monitor and interaction of many sources. This paper provides an preliminary study of Direction Of Arrival(DOA) for outdoor positioning and attempt to classify the different approaches. We focus on Dominant Frequency Selection(DFSE) ,Approximate Maximum Likelihood(AML) and Multiple Signal Classification(MUSIC) methods. We then illustrate and discuss the methods for Direction of Arrival
