The invention provides an electromagnetic environment monitoring system. The electromagnetic environment monitoring system comprises an antenna receiving device, a signal gating device, a frequency spectrum measuring device and a computer control device, the antenna receiving device is used for receiving an electromagnetic field signal through the omnidirectional antenna and the directional antenna; the signal gating device is used for inputting the electromagnetic field signal into the radio frequency switch and controlling the electromagnetic field signal to be alternately output to the frequency spectrum measuring device through the radio frequency switch; the frequency spectrum measuring device is used for measuring the amplitude of the electromagnetic field signal output by the radio frequency switch according to a preset monitoring frequency range and frequency resolution to obtain frequency spectrum data; and the computer control device is used for analyzing the frequency spectrum data to obtain the amplitude and propagation direction of the electromagnetic field signal. By adopting the electromagnetic environment monitoring system disclosed by the invention, the electromagnetic environment can be automatically monitored, the electromagnetic field amplitude of the monitoring area can be displayed, the electromagnetic field propagation direction can also be displayed, and the electromagnetic environment distribution condition can be conveniently analyzed.
Description
technical field [0001] The invention relates to the field of computer application technology, in particular to an electromagnetic environment monitoring system. Background technique [0002] In recent years, with the rapid development of economy and society, the application of high-frequency electronic technology has become more and more extensive, and the utilization rate of electromagnetic equipment has also become higher and higher. At present, the electromagnetic environment is usually monitored by means of a comprehensive field strength analyzer or an antenna (or probe) connected to a spectrum analyzer (or other spectrum measurement device). The existing technology also adds a computer to control the monitoring system, aiming to realize automation monitoring and data processing. However, the above-mentioned various electromagnetic environment monitoring products usually can only measure the amplitude of the electromagnetic field, and the improvement of the products mai...
