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.

Create angle-Doppler response maps to detect objects.
Use displaced phase center antenna (DPCA) pulse cancellation to improve detection in the presence of clutter.
Use adaptive displaced phase center antenna (ADPCA) pulse cancellation to improve detection in the presence of clutter and interference.
Use Sample Matrix Inversion (SMI) beamformer to optimally suppress clutter and jammer interference.
