Query: Study of Sparsity-Aware Reduced-Dimension Beam-Doppler Space-Time
  Adaptive Processing   Existing reduced-dimension beam-Doppler space-time adaptive processing
(RD-BD-STAP) algorithms are confined to the beam-Doppler cells used for
adaptation, which often leads to some performance degradation. In this work, a
novel sparsity-aware RD-BD-STAP algorithm, denoted Sparse Constraint on
Beam-Doppler Selection Reduced-Dimension Space-Time Adaptive Processing
(SCBDS-RD-STAP), is proposed can adaptively selects the best beam-Doppler cells
for adaptation. The proposed SCBDS-RD-STAP approach formulates the filter
design as a sparse representation problem and enforcing most of the elements in
the weight vector to be zero (or sufficiently small in amplitude). Simulation
results illustrate that the proposed SCBDS-RD-STAP algorithm outperforms the
traditional RD-BD-STAP approaches with fixed beam-Doppler localized processing.
