Abstract

The invention relates to a device and method for calibrating an electromagnetic radiometer. The device comprises a calibration signal generating module, an antenna, a fixing support and a calibration error display module. The calibration signal generation module comprises a radio frequency signal generator, a signal amplifier, a directional coupler, a power detection module and a controller. The method includes the steps of adjusting the detection position, generating a zero setting calibration signal, calculating a zero setting error, carrying out zero setting processing, generating a linear adjustment calibration signal, calculating a linear adjustment error, carrying out linear adjustment processing, judging whether the zero setting error is zero or not and the like. By means of the device and method for calibrating the electromagnetic radiometer, the produced electromagnetic radiometer can be rapidly and accurately calibrated in the simple environment.

Description

technical field [0001] The invention designs a calibration device and method, especially a device and method for calibrating an electromagnetic radiation meter. Background technique [0002] With the development of electronic technology, the electromagnetic field environment in the space where people live is becoming more and more complex. Due to the adverse effects of electromagnetic radiation on the body, people wish to know whether the amount of electromagnetic radiation in their environment exceeds the standard. [0003] At present, there are many electromagnetic radiometers for detecting the intensity of electromagnetic radiation in the surrounding environment. The measurement characteristics of the electromagnetic radiation meter are directly related to people's understanding of the surrounding electromagnetic environment. [0004] Electromagnetic radiation meter testing and calibration links are increasingly showing importance in product development and production. ...
