Fast ℓ1-regularized space-Time adaptive processing using alternating direction method of multipliersQin, Lilong (author), Wu, Manqing (author), Wang, X. (author), Dong, Zhen (author)Motivated by the sparsity of filter coefficients in full-dimension space-Time adaptive processing (STAP) algorithms, this paper proposes a fast ℓ1-regularized STAP algorithm based on the alternating direction method of multipliers to accelerate the convergence and reduce the calculations. The proposed algorithm uses a splitting variable to...journal article 2017
