Wideband Adaptive RF Protection (WARP)
Abstract
The Wideband Adaptive RF Protection (WARP) program is developing radio-frequency (RF) front-end technology that can protect wideband digital radios against external electromagnetic threats and self-interference through tunable filtering, limiting, and/or signal cancellation. The ability to create tunable and reconfigurable band pass and band stop filters at microwave frequencies will be important for implementing transmit/receive modules in next-generation multi-function arrays. Another important area of interference mitigation is self-interference. WARP is developing the signal cancellation technology that will listen to the transmitted interfering signal and subtract it from the input of the receiver so faint signals near the noise floor can still be detected. Program research will provide feedback mechanisms that intelligently correct these problems. Whether for self-induced interference or external interference jamming, WARP is developing intelligent filtering and self-interference cancellation technologies to protect wideband DoD receivers.
