This new text, from the bestselling Principles of Space-Time Adaptive Processing (IEE, 2002), discusses various applications of space time adaptive processing, including applications in OTH-radar, ground target tracking, STAP in real world clutter environments, jammer cancellation, supperresolution, active sonar, seismics and communications. The book provides a unique overview of the broad field of space-time processing and is divided into two parts: the first dealing with the classical adaptive suppression of airborne and spacebased radar clutter, and the second comprising miscellaneous applications in other fields such as communications, underwater sound and seismics.
