Title:
超音波受信装置
Document Type and Number:
Japanese Patent JP6404844
Kind Code:
B2
Abstract:
An ultrasonic reception device 10 applied in an object sensing system for transmitting a probing wave which is an ultrasonic wave and acquiring a reception wave including a reflected wave reflected by a peripheral object, the ultrasonic reception device 10 being provided with a wave receiving unit 12 for receiving a reception wave, a frequency measurement unit 14 for measuring the frequency of a reception wave and acquiring the value of the frequency as a measurement value, an amplitude measurement unit 15 for measuring the amplitude value of the reception wave, and a frequency determination unit 18 for determining the frequency of the reception wave as a computed value on the basis of the measurement value acquired in the period taken for the amplitude value of the reception wave to reach a peak value from a rising of the amplitude value.
