Multi-waveform STAP

A new form of Space-Time Adaptive Processing (STAP) is introduced that is amenable to the simultaneous transmission of multiple-input multiple-output (MIMO) emissions from an airborne/space-based platform. Denoted as Multi-Waveform STAP (MuW-STAP or simply μ-STAP), this receive scheme incorporates new sources of training data for the STAP sample covariance matrix through the use of “orthogonal” waveforms optimized for use on a physical system. This additional training data improves robustness to both heterogeneous clutter and target contamination of training data, and also reduces the false alarms that would otherwise occur due to residual clutter.
