Design of the Antenna for AN/SPS-3 (XDK) Hemispheric Radar

Abstract

This report summarized the development work accomplished to date on an 80-degree, dual-beam Foster scanner antenna for the hemispheric radar set AN/SPS-3. The scheme of operation is explained with reference to the MIT Radiation Laboratory sketches which accompanied the original proposal for this system. The basic design changes incorporated during development are: (1) Reorientation of the two pillboxes to permit placing them on a single level in the cone. (2) Introduction of choke-type, back-to-back toothed mirrors. (3) Substitution of magnesium for Fiberglass construction, (4) Use of an integral intermediate shell to provide the necessary strength. The design of a parabolic cylindrical reflector for collimation of the beams in azimuth is discussed. Wind drag and r-f leakage data are presented for tubing-type and edgewise-strip-type surfaces. The latter requires an unusual strip configuration because of the reflector inclination.
