Doppler signal sampling device for automatically tracking signal source, Doppler signal sampling method, and program

摘要

PROBLEM TO BE SOLVED: To provide a Doppler signal sampling device capable of easily and quickly tracking a target located in a subject. SOLUTION: A reception unit 107 that receives distribution information, which is information indicating a distribution regarding a Doppler signal component of a reflected wave with respect to an ultrasonic wave applied to a subject, and a target azimuth located in the subject using the distribution information. The acquisition unit 109 includes an acquisition unit 109 that acquires an angle and a distance, and an output unit 110 that outputs information according to the target azimuth angle and the distance acquired by the acquisition unit 109. The acquisition unit 109 acquires the target distance. After that, the process of acquiring the target azimuth angle using the distribution information received by the reception unit 107 is repeated, and the output unit 110 outputs the information according to the azimuth angle acquired by the acquisition unit 109 after the acquisition of the target distance. I decided to do it. [Selection diagram] Figure 1
