Wideband Adaptive RF Protection (WARP)*
Abstract
*Formerly Instinctual RF The Wideband Adaptive RF Protection (WARP) program will develop 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. Today's advanced wideband DoD systems, such as multi-function phased arrays, are open to all frequencies by design with little or no RF filtering. This is due to a lack of tunable and reconfigurable filters that are small enough to integrate into the arrays, limiting the use of wideband multi-function arrays in contested environments. The ability to create tunable and reconfigurable bandpass and bandstop filters in the range of 2-18 GHz will be important for implementing transmit/receive modules in next generation multi-function arrays. Another important area of interference mitigation is self-interference. Specifically, in electronic warfare, it would be advantageous to be able to receive and perform signal intelligence functions while simultaneously transmitting a high-power jamming self-protect signal. WARP will develop the signal cancellation technology that will listen to the transmitted jamming 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 will develop intelligent filtering and self-interference cancellation technologies to protect wideband DoD receivers.
