PROBLEM TO BE SOLVED: To provide an ultrasonic measuring apparatus, an ultrasonic imaging apparatus, 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. The processing part 130 performs coupling coefficient specification processing for a plurality of first base waves constituting the reception signal for the reception signal corresponding to a transmission pulse signal transmitted by the transmission processing part 110, and performs conversion processing from the reception signal to a reconstitution signal based on a plurality of coupling coefficients specified by the coupling coefficient specification processing and second base waves with a smaller number of base waves than the first base waves.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を提供する。【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、送信処理部110により送信された送信パルス信号に対応する受信信号に対して、受信信号を構成する複数の第1基底波の結合係数特定処理を行い、結合係数特定処理により特定された複数の結合係数と、第1基底波よりも波数が少ない第2基底波とに基づいて、受信信号から再構成信号への変換処理を行う。【選択図】図6
