Abstract
Based on Gaussian model for reflector antenna, the effects of localized wave-front deformation on received power are researched. It is shown that the received power depends on the deepness h, the radius a, and the distance d of the Gaussian distortion and changes regularly as they increase. Localized deformation has the greatest influence on the received power at the deepness of h ≈ 0.38λ, which does not depend on other distortion parameters. To reduce the impact of localized deformation on the received power, the machining precision of mirrors should be much better than 0.38λ. The maximum power penalty due to the localized distortion with different radii a is given. We hope the results can be used in the design of inter-satellite laser communication systems.
