DESIGN AND THEORETICAL PERFORMANCE OF REACTIVEWALL CORNER REFLECTORS.
Abstract
Within the limitations of available materials and a relatively simple design, it is possible to obtain adequate same-sense circularly polarized responses from conventional triple-bounce corner reflectors by modifying a single wall. Minor reductions in coverage occur in one plane, but by proper mounting of the reflector no loss of performance should occur in normal use. The effect of minor variations in dimensions and electrical properties of layer materials should receive further study on an experimental basis. Theoretical calculations indicate such effects to be minor on the basis of assumed tolerances, but preliminary measurements (now in progress) indicate larger variations, possibly due to inhomogeneity. Echo area patterns of production-type reflectors with and without dielectric wall modifications should be obtained and compared with calculated values. The effect of tolerances in wall angles, surface finish and irregular corner profile should be determined independently of the reactive wall modification. Possible losses in performance caused by water absorbed by or flowing over corner surfaces during flight use should be investigated theoretically and experimentally. (Author)
