Adaptive Polarization-Constrained Monopulse Approach for Dual-Polarization Array

Monopulse based DOA and polarization estimation with polarization sensitive arrays

“…The technique makes full use of the array gain with low computational cost and high estimation accuracy, hence it is widely used in practice for radar angle estimation and tracking of one target within the 3dB beamwidth of the sum beam. The monopulse technique has also been studied in polarimetric radar systems for enhanced DOA estimation [34,35,36,37]. However, polarization estimation is performed only by simply comparing received signals from different polarized channels [36,37,38].…”

“…where Ā(θ, ϕ) = A(θ, ϕ)/∥A(θ, ϕ)∥ is the normalized array manifold matrix. Then, F xy = 0(x ̸ = y) can be calculated by (35), and ( 24) can be rewritten as…”
