The Advanced RF Techniques and Systems Group developed a distributed coherent transmit radio system for low-probability-of-detection antijam communications.

Advanced RF Techniques and Systems

Researchers in our group develop new algorithms, architectures, and hardware for radio frequency (RF) systems used for wireless communications, geolocation, and surveillance capabilities. We use our expertise in space-time adaptive processing to develop antijam and low-probability-of-detection communications for military operations in terrestrial, airborne, and maritime environments. Recent research areas have included RF hardware implementation and signal detection, localization, and classification in environments with overcrowded airwaves and frequency conflicts.
