ABSTRACT:
An ultrasonic detecting apparatus which includes a generator which generates more than three transmission signals. The detecting apparatus also includes a transmitter/receiver which transmits waves, which may be ultrasonic waves, to an object and receives echoes corresponding to the transmission signal. A correlator performs correlation operations with respect to the echoes. The results of the correlation operations are processed to obtain a signal with substantially zero side lobes.
