Problems solved by technology
Its theoretical system is abstract, its technical elements are complex, and it is highly professional and academic. For a long time, most of the supporting experiments of this part of the teaching content have adopted the method of virtual simulation, and the means of physical experiments are limited, which seriously affects the improvement of teaching effect.
[0003] If the existing beamforming sonar is moved to the laboratory, not only a large pool is required, the experimental site is expensive, but also the beamforming sonar and sonar equipment are expensive
Therefore, it is difficult and costly to move the existing beamforming imaging equipment to the laboratory for experiments

Embodiment
[0102] The beamforming principle experiment system consists of three parts: display control and processing unit, experiment box and ultrasonic array. The system structure diagram is as follows figure 1 shown.
[0103] (1) Display control and processing unit
[0104] The display control and processing unit is the core of the experimental system, which completes parameter setting, command control, data acquisition and signal processing, and finally completes the display of experimental waveforms and data to realize man-machine dialogue. The display control and processing unit interface displays the original echo and beamforming results.
[0105] When the "Start Playing" button is clicked, the experimental system starts to transmit signals to the target and record echo signals at the same time, and the interface of the display control and processing unit displays the progress of data recording. After the recording progress reaches 100%, the experimental system will stop data r...

The invention belongs to the technical field of experiment simulation, and discloses a beamforming experiment system, an experiment method and high-resolution detection equipment, and a display control and processing system of the beamforming experiment system performs parameter setting, instruction control, data acquisition, signal processing and experiment waveform and data display. The experiment box body performs parameter setting, instruction control, data acquisition and autonomous experiment; the ultrasonic array performs electro-acoustic conversion, converts an electric signal into anacoustic signal during transmission, and converts a multi-channel acoustic signal into a multi-channel electric signal during receiving. Three module-level verification experiments including system clock design, transceiving conversion and time gain control and five independent innovative experiments including pulse distance measurement, DDS, quadrature demodulation, pulse compression and beam forming can be carried out.
Description
technical field [0001] The invention belongs to the field of experiment technology, and in particular relates to a beam forming experiment system, an experiment method and high-resolution detection equipment. Background technique [0002] At present, beamforming is a new type of high-resolution detection technology, which is widely used in economic, social and military information fields. In the teaching of electronic information professional courses in colleges and universities, the beamforming principle has become the core basic teaching content of the detection principle courses. Its theoretical system is abstract, technical elements are complicated, and it is highly professional and academic. For a long time, most of the supporting experiments of this part of the teaching content have adopted the method of virtual simulation, and the means of physical experiments are limited, which seriously affects the improvement of teaching effects. [0003] If the existing beam-form...
