摘要：
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.COPYRIGHT KIPO 2013[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 information아날로그 빔포밍을 효과적으로 하는 방법 및 장치가 개시된다. 이와 같이 개시된 방법 내지 장치에 따르면, 아날로그 빔포밍을 수행할 때, 보다 적은 개수의 소자와 적은 데이터 처리로 높은 수준의 아날로그 빔포밍을 수행할 수 있다.
