The electrical design of plastic buoys containing passive radar reflectors for use in radar navigation is discussed. The specific buoy configuration considered consists of a cylindrical homogeneous wall of uniform thickness Radome enclosing an octahedral radar reflector with the internal space filled with a low-density dielectric foam. Design data are presented to aid in the determination of optimum wall thicknesses and thickness tolerance for a number of candidate buoy wall materials. Computed performance data showing the reduction in radar cross section of the enclosed reflector due to the radome and filling for three orientations of the buoy are presented. A simplified flat-panel model of the radomereflector system is developed which predicts with acceptable accuracy the wall transmission loss as a function of thickness and dielectric properties of the materials.
