Space-Time Adaptive Processing by Employing Structure-Aware Two-Level Block Sparsity

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Traditional radar space-time adaptive processing (STAP) cannot efficiently suppress heterogeneous clutter because of a small number of independent and identically distributed training snapshots.

Deep learning for high‐resolution estimation of clutter angle‐Doppler spectrum in STAP

open access: yesIET Radar, Sonar & Navigation, 2022
Space‐time adaptive processing (STAP) methods can provide good clutter suppression potential in airborne radar systems. However, the performance of these methods is limited by the training samples' support in practical applications. To address this issue,

Fast-time STAP performance in pre and post range processing adaption as applied to multichannel SAR [PDF]

open access: yes, 2006
Hot-clutter cancellation using fast-time Space Time Adaptive Processing (STAP) can occur either pre or post range processing (RP) and to date, there has not been a direct comparison on which method offers the best results. This paper provides an analytic
