A Study on the Generation of Acoustically Bright Zone
초록
This paper deals with a method to generate an acoustically bright zone that has a higher acoustic potential energ than the others. The acoustically bright zone can be generated by optimally excited multiple sources. A method to determine the volume velocity distribution of the sources was presented in this paper. For different applicative purpose, two kinds of cost functions are defined and through the eigenvalue analysis the optimal solution is obtained.
