Abstract

The invention provides a system for measuring the intensity of electromagnetic field at a position to be measured. The system provided by the invention comprises an electromagnetic field intensity sensor which comprises a first assembly and a second assembly, wherein the first and second assemblies are vertical; the first and second assemblies respectively generate a first signal indicating a first field intensity component of the position to be measured and a second signal indicating a second field intensity component of the position to be measured; the system provided by the invention further comprises a field intensity receiver for receiving the first and second signals and calculating the electromagnetic field intensity value of the position to be measured. The method provided by the invention is operated simply and conveniently; data only needs measuring once; the measurement procedure is fully automatic; the measurement time is greatly shortened; and the working efficiency is improved.

Description

technical field [0001] The invention relates to a system for measuring electromagnetic field strength and a method for it. Background technique [0002] In the space electromagnetic field strength measurement industry, in the past, directional antennas such as loop antennas, dipole antennas, and logarithmic periodic antennas were used together with field strength receivers to measure electromagnetic field strength. Due to the vector nature of the space electromagnetic field, when using traditional directional antennas and field strength receivers to measure electromagnetic field strength, the direction of these antennas must be manually or automatically adjusted by servo for multiple measurements to obtain different field strength data, and then multiple Compare the field strength data obtained from the second measurement, select the maximum field strength value, and regard this maximum field strength value as the actual field strength value at a certain point in space. Thi...
