The Tri-Service Radar Symposium (TSRS) is the most prestigious and oldest continuous meeting of defense radar engineers, scientists, and technologists. The TSRS will celebrate its 70th Symposium in 2024.  This event provides an important Tri-Service forum for presenting a wide range of radar technology programs that span research and development through currently fielded systems of the Army, Navy, Marines, Air Force, and Coast Guard. It is the only venue that specifically concentrates on classified and sensitive radar technology and development. Chairmanship rotates yearly among the Army, Navy, and Air Force; the 2024 Symposium is being coordinated and led by the Air Force. This rotation synergistically benefits the services, the broader Government, and Department of Defense (DoD) contractors through peer interactions that enhance the quality of work and stimulate creativity by sharing ideas and progress across services and corporate organizational boundaries. Over the years, participation has grown to include industry and academic partners with the TSRS becoming a truly integrated community event.
