Integrated Wideband Signal Intelligence (SIGINT) Sensor

Although wideband SIGINT receivers are available from numerous sources, they all require other devices to provide SIGINT processing functionality. In addition, they also need other inputs required for SIGINT operations such as GPS, navigation and frequency reference. Presently, such systems require multiple chassis and connections that have duplicate functions and components driving up the cost and system size. The objective of this effort is to develop a small, man-portable wideband Signal Intelligence (SIGINT) sensor with embedded Global Positioning System (GPS) and INS processing to provide a complete SIGINT sensor in a single unit. Our proposed solution is to develop a Wideband Software Defined Radio based on our existing portable Software GPS Receiver design. This allows precise emitter identification and geolocation to be performed using the GPS derived timing and positioning information in a networked architecture. Under the Phase I effort we shall develop a design for a Wide-Band SDR and demonstrate that the design provides adequate digital shielding, RF signal fidelity, low phase noise, high selectivity and dynamic range and consistent RF and digital performance over environmental conditions to support precision signal measurement functions.
