Abstract:

A hybrid numerical-analytical method for computing a correction of uneven parabolic mirror's phase errors by means of secondary meshed reflector is developed. Involving mathematical modelling of random surface distortions an influence of unevenness on antenna directivity has been examined for different correcting reflector's parameters.
