Department of Defense Space Sensor Modernization

Abstract: Future missile threats increasingly stress the sensors used for missile defense. Flying at lower altitudes, they are difficult to track with surface-based radar; detecting them at range will require an architecture of air- or space-based sensors. Masao Dahlgren will present a new CSIS report on Department of Defense space sensor modernization. Informed by modeling and simulation analysis, the report underscores the necessity of diversifying satellite orbits, designing constellations for early, persistent coverage, and retaining requirements for fire-control-capable sensors.
