The invention provides a W-band environmental electromagnetic radiation test method and device. The test method comprises the steps of: selecting a receiving antenna and a frequency spectrograph, and connecting the receiving antenna with the frequency spectrograph through a connector; placing the receiving antenna in a test area. emitting electromagnetic waves into the test area through a tested radiation source; adjusting the position of the receiving antenna, and carrying out electromagnetic radiation power detection; and calculating parameters in the test area according to the electromagnetic radiation power, the parameters comprising power density, electric field intensity and magnetic field intensity. According to the test method provided by the invention, the radiation source emits the W-band electromagnetic wave, the receiving antenna receives the electromagnetic wave, the frequency spectrograph detects the current electromagnetic radiation power, and the power density, the electric field intensity and the magnetic field intensity in the test area can be calculated according to the electromagnetic radiation power and a related formula, so that the detection of the W-band electromagnetic radiation intensity is realized, and the blank of W-band electromagnetic radiation intensity detection is filled.
Description
technical field [0001] The present application relates to the technical field of detection, in particular to a testing method and testing device for W-band environmental electromagnetic radiation. Background technique [0002] At present, the environmental testing department mainly uses electromagnetic detectors / electric field strength testers and other equipment to monitor the electromagnetic radiation / electric field strength / magnetic field strength in the space. Such equipment needs to be equipped with probes with corresponding frequency bands when using them. . The highest operating frequency of high-frequency field strength measuring instruments on the market has reached 60GHz. It can monitor the intensity of electromagnetic radiation with a frequency of up to 60GHz. However, there are no dedicated measuring instruments for higher frequency bands (such as W-band (75GHz-110GHz)). At present, such as reversing radar and other operating frequencies have been applied in 7...
