Abstract: An electronic scanning ultrasonic object-detection apparatus 1 of the present invention comprises; phase control signal generation means 2 for generating a plurality of phase control signals having different transmission frequencies; ultrasonic wave transmission means 3 for transmitting ultrasonic waves of a transmission frequency different from each other by a plurality of arrays, based on the plurality of phase control signals; ultrasonic wave receiving means 4 for receiving reflected waves from an object of the ultrasonic waves with a plurality of receiving elements, judging a signal of the reflected waves received by all the receiving elements as a mail image to thereby output a mail image signal, and judging signals of other reflected waves as side images to thereby output a side image signal; and object-detection means 5 for detecting a position of an object based on the mail image signal output by the ultrasonic wave receiving means 4, and detecting existence of a side image based on the side image sig

Abstract: An electronic scanning ultrasonic object-detection apparatus 1 of the present invention comprises: phase control signal generation means 2 for generating phase control signals having the same transmission frequency; ultrasonic wave transmission means 3 for transmitting ultrasonic waves based on the phase control signals, by a plurality of arrays having a plurality of transmission elements arranged at a constant element interval, with the element interval being different for each array; ultrasonic wave receiving means 4 for receiving reflected waves from an object of the ultrasonic waves, and judging a signal Included in all the reflected waves as a main image to thereby output a main image signal, and judging other signals as side images to thereby output a side image signal; and object-detection means 5 for detecting a position of an object based on the main image signal and detecting existence of a side image based on the side image signal.
