ABSTRACT:
A bi-static communication relay includes a receiver and transmitter carried by different platforms. In particular, the transmitter may be carried by a geosynchronous satellite forming a broadcast platform. The receiver is hidden on a low observable platform, such as an airborne or even a ground based platform forming a hidden platform. The location of the low observable platform is known only to legitimate users of the system. Communications between the hidden platform and broadcast platform are by way of a secure narrow beam uplink to reduce the risk of jamming. Physical separation of the receiver and transmitter essentially defeats the jammer's high power amplifier advantage since the receiver platform is hidden from the jammer. This forces the jammer to use a low gain antenna in order to cover as much sky as possible. System users, on the other hand, can use the gain advantage of a directional antenna, since they alone have knowledge of the hidden platform's location.
