To verify predictions and establish a baseline for comparing analytical results and scan performance, an engineering model with offset confocal paraboloids was designed and built. The model was thoroughly tested and compared with analytically calculated results. The agreement between the measurements and the calculations was remarkable, considering the complexity of the antenna system geometry. The scan peaks, main beams, and sidelobe structures were accurately predicted by the computer program; even for the severe scan cases, the agreement was acceptable.<>
