Abstract
An ultrasonic sensorhas a transmission/reception processing circuit, and the transmission/reception processing circuithas a burst signal transmission circuitthat generates and transmits burst signals S, and a signal processing circuitthat processes reception signals received by a piezoelectric element. The signal processing circuitverifies the reverberation frequency of the reverberation signals of ultrasonic signals (reception signals) reflected to the piezoelectric elementfrom a subject, and on the basis of the verified reverberation frequency and reverberation time of the reception signals, adjusts the frequency of the burst signals Sto be substantially equal to the reverberation frequency, said burst signals being to be generated by the burst signal transmission circuit
