- 摘要：
To reduction unnecessary components in an integration of two-dimensional spectrum data.
SOLUTION: A 2D FFT process section 20 executes a frequency analysis of reception signals, which are repeatedly acquired from the interior of a range gate defining the depth range in a subject and in each of the depth direction and the repetition direction to acquire a two-dimensional POWER spectrum of Doppler frequency. An integration process section 22 integrates the two-dimensional POWER spectrum data along a straight line corresponding to a constant speed to acquire integration data ON the speed. In this case and the integration process section 22 integrates within a limited integration range so as to reduction the unnecessary components in the integration.
