Since its inception in 1991, DARPA’s Microsystems Technology Office (MTO) has been working to create and prevent strategic surprise through investments in compact microelectronic components such as microprocessors, microelectromechanical systems (MEMS), and photonic devices. MTO-derived innovations and advanced capabilities in areas such as wide-band gap materials, phased-array radars, high-energy lasers, and infrared imaging have helped the United States establish and maintain technological superiority for more than two decades.
DARPA published its Young Faculty Award (YFA) 2018 Research Announcement today, seeking proposals in 26 different topic areas—the largest number of YFA research areas ever solicited.
Real-time assessment of the electromagnetic environment can provide a key tactical advantage. The rapid development and proliferation of advanced radios, however, has made this a challenging task. Radio frequency (RF) sensor systems on the modern battlefield must cover many RF and microwave bands through noise and powerful interferers. Ultra-wideband analog-to-digital conversion (ADC) has emerged as an essential technology to interface between propagating analog RF signals and digital processing for reactive decision-making. Such an ADC allows for high-speed and reconfigurable digital processing in a complex electromagnetic environment.
