Design of adaptive matching circuit for sonar system

The functional architecture of sonar system is presented and its various functions are briefly described in order to describe the matching circuit in its context and to mark the matching circuit. The matching circuit can reduce the energy loss and system size of a sonar system by providing the variable reactive power to Sonar system, and also are influenced by the behavior of this load. In this paper, the basic topology of the matching circuit called an adaptive matching circuit is proposed, which is basically composed of variable inductor. First, the power circuit is designed in the power and frequency ranges of interest according to the given specification. Then, the control circuit is also designed through the modeling process. Finally the effectiveness of the proposed matching circuit is proved by using the computer simulation.
