Example Embodiment
[0064] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides detailed implementation and specific operation procedures, but the scope of protection of the present invention is not limited to this Examples.
[0065] Such as figure 1 As shown, the method for determining the pointing error of the wheel-rail reflector antenna includes the following steps:
[0066] S1 For wheel-rail reflector antennas, the azimuth orbit radius is r, the height of the azimuth mount is h, and the distance between the center point of the pitch axis and the vertex of the reflector is h 1 , When the azimuth and elevation angles of the antenna are A and E respectively, the calculation is from the earth coordinate system OXYZ to the reflector coordinate system O r X r Y r Z r The conversion matrix is Z L :
[0067] Z L =Z EJ ·Z AE ·Z φA ·Z Oφ ;
[0068] Z Oφ Is from the geo...
