Annotations languages:

The analysis of statistical methods manyparametric optimization is conducted and the choice of method of "independent" of the global search is justified. An algorithm corresponding to the chosen method of optimization with the given optimized parameters and limits of their variation is constructed. The parameters of the acoustic matching layer and electrical transients correcting circuits were determined, which provide maximum bandwidth.
Keywords: piezoelectric transducer, frequency bandwidth, transfer coefficient, manyparameter optimization
