I2O explores game-changing technologies in the fields of information science and software to anticipate and create rapid shifts in the complex national security landscape. Conflict can occur in traditional domains such as land, sea, air, and space, and in emerging domains such as cyber and other types of irregular warfare. I2O’s research portfolio is focused on anticipating new modes of warfare in these emerging areas and developing the concepts and tools necessary to provide decisive advantage for the U.S. and its allies.
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.
