Abstract: System and method for concurrent STAP (space-time adaptive processing) filtering of interference signals (e.g., jamming signals) from signals received at a broadband antenna array via satellite and terrestrial broadcasts and communication systems operating in the 950 MHz to 1.65 GHz L-band, including but not limited to Link 16 terrestrial communications, Iridium satellite communications, and the Global Positioning System (GPS) and other Global Navigation Satellite Systems (GNSS). While the GPS/GNSS signals are protected against jamming using Nulling of the interfering signals, the Iridium and other communication systems' signals are protected using Beamforming. Use of a common broadband antenna and common front-end signal processing of the received signals enables an integrated system for use on a wide range of platforms, including without limitation size-, weight-, and power-constrained platforms such as drones, unmanned aerial vehicles (UAVs), and helicopters.

Abstract: System and method for concurrently protecting Iridium and GPS L1/L2 band received satellite signals against interference signals (e.g., jamming signals) using space-time adaptive processing (STAP). While the GPS signal is protected against jamming using Nulling of the interfering signals, the Iridium signal is protected using Beamforming. A single broadband small controlled reception pattern antenna (sCRPA) array receives both the GPS (L1 and L2) and Iridium signals for the STAP-based antijam solutions outputting filtered Iridium and GPS signals. Use of a common (small) broadband antenna and common front end signal processing of the received signals enables an integrated system for use on size, weight, and power constrained platforms such as drones, unmanned aerial vehicles (UAVs), and helicopters.
