ABSTRACT:
A missile radome (1) has an acutely pointed profile and includes an antenna array of four elements (A, B) toe'd out around the boresight (5) for an amplitude comparison system. Certain received signals strike the antenna elements (A & B) after grazing the internal radome surface, and after single multiple reflections. The tracking characteristic consequently suffers perturbations. A layer (6) of surface wave absorbent material is provided on the inside of the radome (1) in combination with a mass of radar absorbent material (7) enclosed by this layer. The combination considerably improves the position.
