- Abstract
- The paper treats with the TGFA(time gated frequency analysis) method which is a method for correcting the measured sensitivities of underwater acoustic transducers in a limited water tank. In this paper, the TGFA method is analysed through simulations, and two inequalities are presented as the required criteria for accurate measurement. And, the results of water tank experiments verify the validity of TGFA method for correcting sensitivity..
