The Homeland Sensors and Analytics Group builds technology to counter threats to our critical infrastructure, land and maritime borders, transportation systems, and public places, and to enable US forces to disrupt transnational criminal and terrorist organizations. We focus on the development and fielding of advanced sensors, AI and data analytics, and integrated human-machine decision making to help monitor and characterize these threats. We specialize in prototyping new sensor technologies as well as collecting and processing a wide range of data types — including radar, video, imagery, text, point cloud, transactional, and body-worn sensor data — from both commercial and Laboratory-developed sensors. We often apply advanced machine learning methods to convert raw data into actionable insights about the activities of threat actors, networks, or organizations. Our ultimate goal is to field solutions that significantly enhance the decision-making process of analysts and operators w...
