Abstract

PURPOSE:To quickly derive the three-dimensional velocity vector of a motion reflecting body with high accuracy by setting two receiving beams against a transmitting beam in each scanning face, and calculating a velocity component at every receiving beam. CONSTITUTION:The scanning face 10 is formed, for instance, by scanning electronically an array vibrator in which plural vibration elements are arrayed. Also, in this scanning face 10, two receiving beams 102, 104 for intersecting from each different direction are set against a transmitting beam 100. Moreover, an angle of a two-dimensional velocity vector U against the transmitting beam 100 is shown by theta, and on the other hand, an angle of each receiving beam 102, 104 against the transmitting beam 100 is shown by phi. This angle phi is derived by an expression I. Also, a velocity component UR running along the receiving beam 102 and a velocity component UL running along the receiving beam 104 are shown by an expression II. In this regard, U denotes and absolute value of the velocity vector U.
