Clutter Subspace Characteristics-Aided Space-Time Adaptive Outlier Sample Selection Method [PDF]

open access: yesSensors, 2021
For statistic space-time adaptive processing (STAP), a critical issue is estimating the clutter covariance matrix (CCM). However, sufficient training samples are difficult to obtain that satisfy the independent and identically distributed (IID) condition. It is because of the realistic heterogeneous environment faced by airborne radar.
