Lincoln Laboratory Journal
About the Journal
The Lincoln Laboratory Journal showcases some of the Laboratory's most innovative and high-impact work, in fields ranging from air traffic control to bioagent sensing to parallel computing. The Journal consists of in-depth feature articles written by Laboratory staff members as well as shorter "Lab Notes" written by the Journal editors.

A cognitive-based strategy for transmission channel access addresses the need for an approach that is spectrally agile and efficient under scarce resources and that is resilient to adversarial threats. The strategy’s five key components—sensing, learning, optimizing, transmitting, and jamming—are combined to model a tactical communications network, and game-theoretic algorithms and a performance metric are employed in a hypothetical blueforce versus red-force competition for spectrum resources.

Lincoln Laboratory has developed a digital pixel focal plane array with per-pixel, 16-bit full dynamic range, analog-to-digital conversion, and real-time digital image processing capability. The technology leverages modern semiconductor processes to achieve low-power, high component-density designs. Infrared sensors based on this innovative technology are enabling very-wide-area, high-resolution, high-sensitivity, high-update-rate imaging, as well as novel sensing modalities.

Wavelength beam combining allows for scaling the power of a laser system in a modular approach while preserving the quality of the combined beam. Lincoln Laboratory has demonstrated a wavelength-beam-combining technique that significantly improves the brightness and intensity achieved by diode laser systems. This technology could lead to diode lasers’ replacing other types of lasers in industrial applications such as metal cutting and welding.
LLCySA: Making Sense of Cyberspace
Scott M. Sawyer, Tamara H. Yu, Matthew L. Hubbell, and B. David O’Gwynn
Today’s enterprises require new network monitoring systems to detect and mitigate advanced cyber threats. The Lincoln Laboratory Cyber Situational Awareness (LLCySA) system gives network operators insights into the current state of an enterprise-scale network and provides cyber analytics researchers a platform for algorithm development. LLCySA includes highly scalable data warehousing, real-time data ingestion, responsive querying for both human users and automated analytics, and the computational capabilities required by advanced algorithm.
