With the Kronecker product structure constraint, this paper proposes a covariance matrix (CM) estimation method in Compound-Gaussian (CG) sea clutter background. We assume CG different polarization channels has textures, which is from existing structure-based CM methods for polarimetric target detection. Based on maximum likelihood (ML) criterion, we obtain fixed point equation of and solve it by an iterative algorithm. The proposed referred to as Kronecker-based estimate (KMLE), relevance...
This paper proposes a reduced-dimension polarization-space-time adaptive processing (RD-PSTAP) algorithm for airborne conformal array (CFA) radar to achieve better clutter suppression performance at lower computational complexities. Firstly, we take polarization information into signal modeling. Subsequently, the dimension reduction matrix is derived based on generalized sidelobe cancellation (GSC) structure, which incorporates of target and constructing main channel auxiliary channels,...
