Sonar system and impedance matching method thereof

摘要: This specification relates to an active SONAR system comprising a transmitter, transducer and impedance matching circuit for expanding bandwidth increasing power factor value in sound ultrasonic wave bands by mutually resonant frequencies of the or frequency between using electrical equivalent model corresponding actual data controlling positions intervals at which reactance components including become zero, method thereof. allows efficient driving broadband transmitter system, contributing output performance detection system.
