The influence of the amplitude weighting coefficient of the transmitted signal and the emission sensitivity of the array element on the constant beamwidth and the constant power transmission of the broadband hydroacoustic signal with the variation of the frequency is analyzed. A broadband matching network consisting of coupled resonant circuits coupled by multiple resonant circuits is adopted. Programming signal source and broadband power amplifier and other technical methods, the use of coupled resonant circuit for the wideband signal better frequency selectivity and digital programmable signal source processing flexibility of the transmitted signal to ensure that the broadband water acoustic signal required constant beam Wide and constant power emission.
