Space-Time Adaptive Processing

DPCA and ADPCA pulse cancellation, sample matrix inversion (SMI) beamforming

Signals received by a phased array are often overwhelmed by interference or background clutter. Clutter is called reverberation in acoustic applications. Phased Array System Toolbox™ algorithms perform space-time adaptive processing (STAP). STAP processing combines temporal and spatial filtering to nullify interfering jammers. You can use STAP processing to detect slow-moving or stationary targets in background clutter.
