ABSTRACT:
A method for predicting and compensating for angular beam misalignment of an antenna (101) due to antenna shape distortion resulting from gravitational effects. Measured (701, 702) antenna shape data in a target gravity loading environment and several test environments (600-603) are used to compute expected antenna beam misalignment angles in the test gravity loading environments (600-603). Actual antenna beam misalignment angles are measured (705) with the antenna (101) positioned in each of the test gravity loading environments (600-603). The expected antenna beam misalignment angles (704) are combined (707) with measured beam misalignment angles (705) to predict the beam misalignment of the antenna (101) in the target gravity loading environment. If the antenna (101) is an adjustable type, then the antenna (101) can be deliberately misaligned on the test range so that it will be properly aligned in the different gravity condition of the target environment. Further, thermal shape distortion data (706) can be incorporated to predict beam misalignment due to thermal distortion as well.
