A STAP configuration for airborne surveillance radars

This paper presents a space-time adaptive processing (STAP) configuration for affordable airborne systems with practical apertures to be operated in real environments. In contrast to other STAP approaches relying on the spatial DOF (degrees of freedom) reduction, this configuration creates the system's available spatial DOF as close as possible to what is needed from the beginning. In addition, it includes pre-suppression of wideband noise jammers (WNJ), sample selection and conditioning, and scan-to-scan track-before-detect (SSTBD) processing. Its main functional blocks are discussed in detail.
