Abstract

The cover for the radar antennas of missiles consists of a plurality of dielectric hollow bodies which are arranged concentrically with respect to one another, the outermost hollow body being firmly connected to the outer wall of the missile; the distance between the outermost hollow body and at least one of the inner hollow bodies is variable via a control device. <IMAGE>
