Zusammenfassung:	PROBLEM TO BE SOLVED: To provide improved technologies for the weighting in reception of array transducers. SOLUTION: In Figure (A), a receiving beam 102 is formed by using a weighting function 112. The position of the peak of the weighting function 112 is the position of the receiving beam 102. A receiving beam 104 is formed by a weighting function 114, and the position of the peak of the weighting function 114 is the position of the receiving beam 104. A receiving beam 106 is formed by using a weighting function 116, and the position of the peak of the weighting function 116 is the position of the receiving beam 106. In this way, the positions of the weighting functions 112, 114 and 116 are shifted within a receiving opening to follow the movement of the receiving beams 102, 104 and 106 by the electronic scan.
