PROBLEM TO BE SOLVED: To provide an ultrasonic measuring device, an ultrasonic imaging device, an ultrasonic measuring method, etc. capable of improving not only azimuth resolution in a measurement result of an object by an ultrasonic wave, but also distance resolution.SOLUTION: An ultrasonic measuring device 100 includes a transmission processing part 110 for performing the transmission of an ultrasonic wave to an object, a reception processing part 120 for performing reception processing of an ultrasonic echo for the transmitted ultrasonic wave, and a processing part 130 for performing processing for a reception signal from the reception processing part 120. For the reception signal, the processing part 130 performs specification processing for reflection intensity from a point scattering body in the object based on M (M being an integer of two or more) base waves in which phases of at least two base waves of M are mutually deviated by a phase difference shorter than a phase difference corresponding to a pulse width of a transmission pulse signal transmitted by the transmission processing part 110 or a pulse width of the reception signal for the transmission pulse signal.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2016,JPO&INPIT【課題】 超音波による対象物の測定結果の方位分解能だけでなく、距離分解能も向上させることができる超音波測定装置、超音波画像装置及び超音波測定方法等の提供。【解決手段】 超音波測定装置100は、対象物に対して超音波を送信する処理を行う送信処理部110と、送信した超音波に対する超音波エコーの受信処理を行う受信処理部120と、受信処理部120からの受信信号に対して処理を行う処理部130と、を含む。そして、処理部130は、M個(Mは2以上の整数)の基底波のうちの少なくとも2個の基底波が、送信処理部110により送信された送信パルス信号のパルス幅又は送信パルス信号に対する受信信号のパルス幅に対応する位相差よりも短い位相差で、相互に位相がずれているM個の基底波に基づいて、受信信号について、対象物内の点散乱体からの反射強度の特定処理を行う。【選択図】 図6
