Problems solved by technology

The direct signal is the signal to be measured, but the reflected and scattered signal interferes with the direct signal and affects the measurement result of the direct signal, so the measuring instrument has an impact on the measurement result
Due to the many factors related to the influence of the measuring instrument on the measurement results, the measurement results cannot be calibrated

Abstract

The invention discloses an electromagnetic environment monitoring device free from instrument influence, and relates to an electromagnetism measuring device. The electromagnetic environment monitoringdevice comprises a measuring instrument (20), a cable (21), a measuring antenna (22) and an absorbing carpet (22); the measuring antenna (22) is located on the outer part of the measuring instrument(20), one end of the cable (21) is connected with an input port of the measuring instrument (20), and the other end of the cable (21) is connected with the measuring antenna (22); the front surface ofthe absorbing carpet (30) is provided with a plurality of absorbing wedges (31); the measuring instrument (20) is covered with the absorbing carpet (30); a metal layer is arranged on the bottom surface (32) of the absorbing carpet in an attached mode, and the bottom surface faces the covered measuring instrument (20); and the absorbing carpet (30) can absorb electromagnetic wave irradiated to theabsorbing carpet (30). The electromagnetic environment monitoring device can reduce the influence of the measuring instrument (20) on a measuring result.

Description

technical field [0001] The invention relates to an electromagnetic measuring device, in particular to an electromagnetic environment monitoring device free from instrument influence. Background technique [0002] The task of electromagnetic environment monitoring is to measure the electromagnetic energy of its environment. In order to ensure the accuracy of the measurement results, in addition to the requirements for the measuring instrument itself, the national standard for electromagnetic environment measurement also stipulates the surrounding environment of the testing instrument. The national standard stipulates that the measuring instrument should be in an open area to avoid the uncertain factors of the surrounding environment of the measuring instrument from affecting the measurement results. With the development of economic construction, especially mobile communication, the task of monitoring the electromagnetic environment of base stations is becoming more and more ...
