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 moving target display is moved to the laboratory, not only the large-scale experimental site is expensive, but also the moving target display equipment is expensive
Therefore, moving the existing moving target display equipment to the laboratory for experiments is difficult and costly

Embodiment 1
[0101] The experimental system of moving target display principle consists of four parts: display control and processing unit, experimental box, transducer unit, rotating motor and target track. The system structure diagram is as figure 1 shown.
[0102] (1) Display control and processing unit
[0103] 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, and realizes man-machine dialogue. The interface of the display control and processing unit is divided into two parts: the left part is the original echo display window, and the right part is the moving target display result display window.
[0104] When the "Start Play" button is clicked, the experimental system starts to transmit signals to the target, and at the same time starts to record the echo signals, and the progress of the data r...

The invention belongs to the technical field of experiment simulation, and discloses a moving target display principle experiment system, an experiment method and a moving target display device. A display control and processing system of the moving target display principle experiment system performs parameter setting, instruction control, data acquisition, signal processing and experiment waveformand data display; an experiment box body performs parameter setting, instruction control, data acquisition and autonomous experiment; a transducer unit performs electro-acoustic conversion, convertsan electric signal into an acoustic signal during transmitting, and converts the acoustic signal into an electric signal during receiving; a rotating motor drives the transducer to perform fan-shapedscanning; a target track drives a target to move to simulate the moving target. According to the invention, three module-level verification experiments of system clock design, transmit-receive conversion and time gain control and five autonomous innovative experiments of pulse ranging, DDS, quadrature demodulation, pulse compression and moving target display can be carried out.
Description
technical field [0001] The invention belongs to the field of experiment technology, and in particular relates to a moving target display principle experiment system, an experiment method and a moving target display device. Background technique [0002] At present, moving target display is a kind of detection technology, which is widely used in the fields of economic society and military information. In the teaching of electronic information professional courses in colleges and universities, the principle of moving target display 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.
