Abstract:

The feasibility of tracking the Project Mercury capsule with active radars depends on the radar scattering characteristics of the capsule. Radar backscatter cross sections of the Project Mercury capsule were measured by standard modeling techniques at simulated radar frequencies of 440, 933.3, 1184, 2800, and 5600 mc, and for climb angles alpha of 0, 15, 30, 45, 60, 75, and 90 degrees. Both horizontal and vertical polarizations were used. The largest backscatter cross section sigma over the widest angular intervals were obtained at 933.3 and 2800 mc. Values of delta were somewhat higher at 933.3 mc than at 2800 mc. Author
