text: Apparatus for measuring deviations from a predetermined value, of the electrical thickness of a dielectric radome of elongated generally ogival form adapted to pass a beam of electromagnetic energy therethrough, comprising means yfor supporting said radome in test position, a microwave energy source adapted to pass a test beam of microwave energy through the wall of said radome in test position with predetermined relative incidence angle, polarization and spacing of said source in relation to said radome wall, a microwave energy receiver positioned fixedly in relation to said source in said beam to receive microwave energy from said source after passing through said wall, said support means including means to move the radome generally longitudinally thereof and to -rotate said radome about the longitudinal axis thereof to produce relative motion between said wall and said source in the general plane of said wall where it is intersected by said test beam for systematically scanning said wall relative to the source and receiver while maintaining the relative test beam incidence angle, polarization and spacing of the wall relative to the source, and means to indicate variations in relative electrical phasing between microwave energy directly from said source and microwave energy received in said receiver after passing through said wall, said support means comprising curved track means extending generally longitudinally alongside of the elongated radome, and carriage means rotatively supporting the radome `and engaging said track means to move said radome generally longitudinally of itself along said track means, the source and receiver being positioned relative to said track means to direct the microwave energy test beam through a side of said radome removed from said track, said track being generally curved in conformity with the longitudinal curvature of said radome side and in a plane generally parallel to the longitudinal plane of curvature of said radome side, thereby -to maintain Aconstant said relative test beam incidence angle, polarization and spacing throughout longitudinal movement of said radome.
