Abstract: PURPOSE: A device and a method for performing analog beamforming are provided to reduce a memory, the operation quantity of a system, and the number of hardware devices for transmitting ultrasonic signals. CONSTITUTION: A device for performing analog beamforming comprises a delay control part(707) outputting first control information showing delay times of first unit time and second control information showing delay times of second unit time about an ultrasonic signal at a position within a predetermined scan area; a first analog device which delays or passes a received ultrasonic signal based on the first delay control information for the first unit time; a second analog device which delays or passes an ultrasonic signal which is delayed or is passed based on the second delay control information for the second unit time; and a combiner(704) adding up ultrasonic signals postponed by the second analog device. [Reference numerals] (701) One dimension transducer arrangement; (702) Switching part; (703) Receiving signal delaying part; (704) Analog combiner part; (705) Switching control part; (706) Control part; (707) Delay control part; (708) Clock generation part; (709) AD converter; (710) Digital beam forming part; (711) Residue signal removal part; (AA) Input scan start command; (BB) Image information
