A proposed far-field method for frequency-stability measurements on the DSS 13 beam-waveguide antenna

A method for measuring the frequency stability of the beam-waveguide (BWG) antenna at Deep Space Station 13 is presented. This method is relatively inexpensive and primarily utilizes equipment that is already available. Another desirable feature of the method is that a far-field signal will be used for the measurement. In concert with the goal of employing new technology developments, a fiber optic system will be used at 12 GHz to carry a reference antenna signal to the BWG antenna Ku-band test-package location in the pedestal room.
