A Novel Method of Detecting Leading Edge of Ultrasonic Echo

摘要：

A novel method which modulates the information of the leading edge to the working frequency of the ultrasonic. We adopt the instantaneous frequency leap to locate the leading edge of the echo through the FSK modulation, the precise position of the leading edge can be detected by measuring the change in instantaneous frequency of echo. One fundamental difference between our new method and generic method resides exactly in that we choose frequency as our detect object for its good capability in anti-noise.
