Instinctual RF
Abstract
The Instinctual RF 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, or signal cancellation. Today's multi-function phased arrays that cover broad bandwidth are open to all frequencies with little or no RF filtering. This is due to a lack of reconfigurable filtering that is small enough to integrate into the arrays, limiting the use of wideband multi-function arrays in contested environments. The ability to create reconfigurable bandpass and bandstop filters in the range of 2-18 GHz will be important to 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 listen while jamming. Instinctual RF will develop the signal cancellation devices that will listen to the transmit signal and subtract the interfering signal from the input of the receiver so that it will be able to hear faint signals near the noise floor. Instinctual RF research will provide feedback mechanisms that instinctively correct these problems, much like the nerves of the human body serve to trigger protective action without conscious thought. Whether for self-induced interference or external interference jamming, this program will show the ability to auto-correct and allow for continued operation.
