Abstract

The present invention relates to an antenna leveling method and system. An embodiment of the system includes: at least three distance measuring units; each distance measuring unit in the at least three distance measuring units is arranged on the edge of the bottom surface of the antenna platform , the signal transmission direction of each ranging unit points to the ground; wherein, each ranging unit is used to obtain the distance between it and the ground; the distance obtained by the at least three ranging units is used for comparison: in the comparison result If they are the same, it means that the scanning surface of the antenna is parallel to the ground; if the comparison result is different, adjust the attitude of the antenna until the comparison result is the same. This embodiment can use the distance measuring unit to realize antenna leveling, and solve the problem of different radiation gains received by the target due to the different heights at the beginning and end of antenna scanning in the existing near-field electromagnetic test.

Description

Technical field[0001]The present invention relates to the field of antenna, in particular, to an antenna leveling method and system.Background technique[0002]The near field electromagnetic measurement system belongs to the in-vehicle measurement system, the measurement method is an antenna to move scan targets in approximate horizontal movement. Electromagnetic waves are spoon distribution in the radiation gain in the vertical surface direction in the target.figure 1 The antenna radiation gain varies from the height (i.e., the distance between the antenna and the ground) (the abscissa is a radiation gain, the ordinate is height), it can be seen that the height difference is 0.2m, the gain difference can reach 6.325dB, visible antenna height Differences can result in different measurement data in different radiation gains. The following problems were found during the test: First, due to the one end of the frontline scan track of the frontline of the antenna platform (i.e., the platfo...
