The invention provides an error estimation method and device for a planar near-field measurement device and a storage medium, and relates to the technical field of antenna measurement, and the method comprises the steps: determining at least one standard antenna used for evaluating a to-be-measured antenna from a preset antenna list; respectively determining a first mechanical error parameter and a second mechanical error parameter according to a second tolerance error and a third tolerance error which are closest to the first tolerance error of the to-be-tested antenna in the sample data of the standard antenna so as to determine a third mechanical error parameter; calculating a fourth tolerance error corresponding to the third mechanical error parameter according to antenna sampling data of the sample data; repeating the selection of the third mechanical error parameter and the calculation of the fourth tolerance error until the difference value between the fourth tolerance error and the first tolerance error meets a preset condition; and according to the final third mechanical error parameter, determining an installation reference parameter of the planar near-field measurement device. The equipment and the storage medium apply the method, and the installation reference parameters can be quickly determined to build a test environment.
Description
technical field [0001] The present application relates to the technical field of antenna measurement, and in particular to an error estimation method, device and storage medium of a planar near-field measurement device. Background technique [0002] Planar near-field measurement is to use an electrically small antenna or probe with known characteristics to collect the amplitude and phase distribution of the antenna under test on a plane at a certain position from the antenna under test, and then obtain the far-field radiation performance through theoretical calculation. In the actual measurement process, the amplitude and phase distribution of the antenna to be tested is affected by the installation error of the measuring device’s probe, the mechanical error of the stepping motor, etc., resulting in the unreliability of the collected far-field radiation performance data of the amplitude and phase distribution, and due to different antenna types The difference in tolerance er...
