Background: NATO recognizes that the space domain is increasingly important to the Alliance and Allies’ security and prosperity. They recognize that space is becoming more crowded and contested and that satellites are vulnerable to emerging counterspace capabilities and intentions. In response, NATO adopted a new Space Policy and declared space an operational domain. A key NATO need to meet the evolving space threat is a dynamic understanding of space activities or Space Domain Awareness (SDA), particularly, a tactical awareness of maneuvering satellites and multiple satellites in close proximity to NATO assets.
 
Ground-based optics and radars are the dominant sensors employed for Space Domain Awareness; however, optical sensing is hampered by inclement weather and by solar exclusion / daylight periods where radar has a 24/7 capability. For military operations, in which tactical surveillance is often required, radar sensing (both active and passive) is well suited to meet these demanding requirements. For the case of tracking objects in Geosynchronous (GEO) orbits, where radars typically have limited operational range, this disadvantage can be overcome using long integration periods and/or adjunct high gain antenna receivers in bistatic configurations.
 
As Space Domain Awareness is fundamental to understanding all activities in space that may help or endanger NATO missions, this lecture series seeks to give an overview of the SDA area (satellite types, orbit regimes and orbital dynamics) followed by an in depth discussion of how radar systems are employed for SDA, including new concepts for enhanced SDA.
Objectives: The goal of this Lecture Series, Active and Passive Radar Systems for Space Domain Awareness, is to provide to a wide military and civil audience, first, an overview and understanding of the challenges associated with achieving Space Domain Awareness and then, an in depth understanding of radar system fundamentals, signal processing and cutting-edge applications for addressing target detection, tracking and characterization to meet SDA.
