High Frequency (HF) communications systems and radars are in widespread use around the world. Accurate standoff geolocation and characterization of these sources are difficult because of ionospheric variations, the high noise environment that exists at these frequencies, and ionospheric polarization rotation, multipath-induced signal fading, and simultaneous multiple angles-of-arrival. Recent advances in high dynamic range receivers, antenna techniques, adaptive signal processing, and ionospheric ray path prediction, along with improved measurement and modeling techniques suggest that a dramatic improvement in HF reception and geolocation is possible.
- Developing and prototyping technology to provide a dramatic improvement in the ability to geolocate and characterize HF emitters
- Enhancing signal-to-noise ratio (SNR), signal detection and source geolocation with multi-dimensional adaptive signal processing
- Resolving multiple angles-of-arrival and polarization states through novel antenna concepts
