Description

technical field [0001] The invention belongs to the technical field of electromagnetic wave measurement, and in particular relates to a high-precision large-area electromagnetic field two-dimensional spatial field distribution scanning device and method. Background technique [0002] The development of modern communication, radar, wireless energy transmission and other technologies must rely closely on precise measurement technology and its corresponding test system. This is because various numerical or analytical methods are designed by modeling and solving electromagnetic field problems. The results can only be used as a reference. The actual situation is affected by the environment, processing technology, etc., and it is difficult to achieve the ideal state of simulation. Only through the combination of actual measurement and simulation can we get more objective and accurate results. Moreover, measurement technology is also A supplement to the design theory, the defects i...

Problems solved by technology

Some literature proposes to use UAV-borne measurement system to measure space electromagnetic field. Although this method can realize measurement in a large measurement range, it has low measurement accuracy, low positioning accuracy, poor endurance of UAV, and is not suitable for Electromagnetic field distribution measurement scenarios such as high-power wireless energy transmission and high-power microwave weapons are prone to electromagnetic compatibility problems
