| Abstract: | Different arranged transducer determines the directional property of a transducer array. Multibeam pivotal technology the basis of Beam forming is how to control the directional property of transducer. This article summarizes the theory of beam forming with mathematics operation for different type of transducer, and introduces a universal way of frequency domain beam forming by using 2-dimension DFT. Finally, the author simply explains the different beam forming technology which the multibeam have in use. |
