Electromagnetic wave imaging and measurement system based on wireless transmission control

  • In order to provide a portable electromagnetic wave measurement system scheme based on vector network analyzer (VNA) as a platform for teaching or Scientific research department, an electromagnetic wave imaging and measurement system based on wireless transmission control was designed. Through the mobile device as the client and the ESP8266 module as the server, the wireless transmission control of the measurement system is realized. The server is connected to the vector network analyzer and the motor drive control circuit for parameter setting and data acquisition, and processes the collected data through corresponding algorithms to realize electromagnetic wave imaging and measurement. The system uses wireless transmission for data interaction to isolate the user's test environment from the precision instrument, which not only protects the instrument, but also greatly improves the use efficiency of the instrument. The actual measurement results show that the test system can accurately image the surface wave of the object to be measured by electromagnetic waves, and the test results are consistent with the simulation.
