Inverse beamfoming applied to circle array

WANG Liang SONG Zhi-Jie (Physics Department,Ocean University of China,Qingdao 266100)  
The inverse-beamforming method is applied in circle array in this paper, the approximate solutions of the FIM(Fourier Integral Method)integral equation is given and the beamforming algorithm is improved by use of the moving average.From simulation:the side lobe is 4dB lower than that of the conventional beamforming and the space resolution is raised by about 1/3.The performance of algorithm is confirmed through treating the data of a sea experiment.
