ABSTRACT:
The radio-frequency performance at localized areas of a radome is determined by a method which includes illuminating at normal incidence a local radome patch with a sweep-frequency band of microwaves having a frequency band of at least two-thirds octave surrounding the design frequency of the radome. Alternatively, a harmonic band of three times the design frequency band may be utilized in the method when compact equipment is important. A sweep-frequency generator is coupled to a reflectometer for response to the band of illuminated and reflected microwaves from a local radome patch to provide an X-Y plot of reflectivity as a function of the sweep-frequency. The sweep-frequency is related to scan angle using known radome equations.
