Ultrasonic wind finding system and method

The invention discloses an ultrasonic wind finding system and method. The system is composed of ultrasonic transducer probes, a circuit board, a pedestal, and a reflection plane. The ultrasonic transducer probes are used for transmitting and receiving pulse signals having set lobe widths; each two ultrasonic transducer probes are opposite to each other and form one group; a connecting line between each two ultrasonic transducer probes opposite to each other is marked as a connecting wire; and at least two groups of connecting wires in the system are perpendicular to each other. An ultrasonic wave emitted by the ultrasonic transducer probe in each group is reflected by the reflection plane and then can be received by the other ultrasonic transducer probe in the same group as the ultrasonic transducer probe and only can be received by the other ultrasonic transducer probe in the same group as the ultrasonic transducer probe. Using the method and system provided by the invention, accuracy of a measuring result i
