Advanced concepts in STAP

Multidimensional colored-noise matched filtering is utilized in a broad range of applications for target detection. It is now common to call this filtering space time adaptive processing (STAP), a term originally used to describe the mitigation of ground clutter in the airborne radar application. This paper examines issues related to signal representation in multidimensional spaces and noise field estimation. Recently developed concepts are examined and emerging areas of research in STAP are discussed.
