Abstract
An attenuation device for use under a radome disposed on a mobile platform such as an aircraft for reflecting a portion of the electromagnetic energy radiated by an antenna disposed under the radome such that the reflected portion of energy impinges the radome at an angle normal thereto, thereby reducing or eliminating further reflections of the reflected portion of energy within the radome toward the mobile platform. In one embodiment the radome includes a base covered with a radar absorbing material (RAM). In another embodiment the radome includes a curved base adapted to match the mobile platform surface curvature on which the attenuation apparatus is mounted. In a further embodiment, RAM is disposed on an exterior surface of the mobile platform under the radome. In still another embodiment, the base is formed of an attenuating transverse magnetic TM wave corrugated plate.
