Abstract: A system for augmenting 360-degree aspect monostatic radar cross section of an aircraft. The system may comprise a pair of pods mountable on opposing wing tips of an aircraft and each having a pod housing with an elongate body tapering forwardly to a nose and rearwardly to a tail. Each pod may comprise a forward SDL disposed within the nose, a rear SDL disposed within the tail, and a pair of mid-body SDLs disposed within a mid-section of the pod housing. The SDLs may be arranged within the pods to reflect radiation and provide coverage around the aircraft over a region of about 360 azimuth degrees. Each SDL may comprise radar absorbing material located on an interior reflective surface, and portions of the elongate bodies may be constructed of radome material. The SDLs may be Luneburg lens having diameters of at least approximately 8-inches.

Abstract: In an active radar augmentation system a microwave switch is connected been the receiving antenna and the amplifier. When there is an RF input signal to the receiving antenna of the augmentation system, a square wave timing signal provided to the microwave switch is adjusted to have the microwave switch in an open state during a time period when the coupling or feedback signal from the transmitting antenna of the augmentation system is received by the receiving antenna. The "on-off" timing of the square wave signal is set equal to the external time delay of the feedback signal plus the internal time delay of the RF signal as the RF signal passes through the augmentation system. Under this condition, the feedback signal coupled by antenna leakage arrives at the output of the receiving antenna while the microwave switch is in the open state.
