Embodiment Construction
[0040] The present invention will be further described below in conjunction with accompanying drawings and examples of implementation.
[0041] refer to figure 1 , the present invention is based on the far-field deformation reflector antenna phase center correction method, and its implementation steps are as follows:
[0042] Step 1, using the best matching parameters of the deformed reflective surface, the total optical path difference of the aperture surface of the best matching paraboloid is established.
[0043] figure 2 A schematic diagram of the best matching paraboloid OX'Z' plane of the reflector antenna is given. In the figure, OX'Z' is the coordinate system whose origin is located at the fixed point of the ideal reflector, and OX' 1 Z' 1 is the coordinate system whose origin is at the fixed point of the best fitting paraboloid, o 0 is the focus of the ideal reflector, o 1 is the feed position after antenna deformation, o 2 is the focus of the best fitting para...
