FENG Haihong;LIANG Guolong; HUI Junying (Dept. Of Underwater Acoustic Engineering, Harbin Engineering University Harbin 150001)  
As known, a hydrophone with small size has no ability to estifnate the object direction. But a small combined sensor with pressure and particle velocity can estimate the direction of an object effectively. The direction maximum likehood estimation using combined sensor as well as experiments in a lake is shown in this article.
