AI Technical Summary

Problems solved by technology

[0004] The wavelength of high-frequency electromagnetic waves is short, which is short-wave or even microwave. Due to the short distance between each peak and trough, the diffraction ability is weak, and it is easily blocked and scattered by obstacles in the air. It is necessary to obtain the microwave scattering value and correct the detection signal in order to effectively obtain the microwave signal. However, the existing long-distance microwave signal acquisition device is not accurate enough, and cannot effectively detect the microwave scattering value, and cannot effectively eliminate signal interference.
