High Frequency Geolocation (HFGeo) Phase 2 and 3

The HFGeo Program aims to dramatically improve the ability to detect and geolocate HF emitters. Phase 1 of the program addressed technical innovations to accomplish this objective including 1) the ability to  accurately resolve multiple angles-of-arrival and polarization states through novel antenna concepts; 2) the ability to enhance signal-to-noise ratio and signal detection through the use of multi-dimensional adaptive signal processing; and 3) the ability to accurately determine the dynamic state of the ionosphere. These components were addressed by two prior solicitations, IARPA-BAA-11-07 and IARPA-BAA-12-04.

Phase 2 includes system integration of these innovations followed by a non-real-time field test. Phase 3 will be real-time implementation and demonstration with field testing. Phase 2 will be 18 months, and Phase 3 will be 15 months in duration. Phase 2 provides the transition from the key technologies of Phase 1 to the development of a prototype system of hardware and off-line signal processing for use in initial field tests with surrogate targets. Phase 3 will implement real-time signal processing, incorporate signal processing enhancements and test against realistic targets in realistic environments.

This BAA only covers HFGeo Phases 2 and 3.
