Sensors DirectorateOur MissionRobust sensors and adaptive countermeasures that guarantee complete freedom of air and space operations for our forces, and deny these capabilities to our adversaries at times and places of our choosing.To lead the discovery, development, and integration of affordable sensor and countermeasure technologies for our warfighters.
Our Vision
-
Sense, identify, and track all air and surface targets and threats world wide and in all weather
Counter difficult targets (WMD, hidden, LO)
Protect air and space assets
Control the battlespace electromagnetic spectrum
Rapidly prosecute time-critical targets and threatsPriority Warfighter Needs Being Addressed by Sensors Directorate Balance: Performance & Affordability

ATR Theory GoalsPerformance PredictionAlgorithm (or feature) dependent As a function of sensing, target, and environment conditionsTool for developers (how will this new feature help?), maturers (does this work well enough for my application?), and users (is this system going to work in my scenario today?)Performance BoundsAlgorithm independent performance limitsAs a function of sensing, target, and environment conditionsIs the limit the algorithm (keep working) or the sensor (motivate sensor improvements)?Performance ModelsPackaged tools from Performance Prediction usable by sensor management and fusion algorithms to weigh sensor contribution
