DARPA Awards BAE Systems Two Awards under WARP Program BAE Systems will design mechanisms for the U.S. Defense Advanced Research Projects Agency (DARPA) that protect emerging wideband receivers from interference, enabling their use in contested and congested environments. DARPA awarded two contracts to BAE Systems totaling $5 million under the Wideband Adaptive RF Protection (WARP) program which is designed to develop wideband adaptive filtering and signal cancellation architectures to safeguard emerging wideband receivers against both external and self-interference. Within the Department of Defense, radio frequency (RF) systems must operate within an increasingly crowded electromagnetic spectrum and contend with mission-compromising interference from friendly and hostile sources.
