Anti-jamming Algorithm of Polarization Sensitive Array Based on Orthogonal Subspace Projection

This paper investigates the orthogonal subspace projection-based adaptive anti-interference technique for polarization-sensitive arrays. The mathematical model of the polarization-sensitive array adaptive anti-jamming and the orthogonal subspace projection algorithm are introduced first, followed by the derivation of the orthogonal subspace projection anti-interference algorithm. The simulation results demonstrate that the orthogonal subspace projection algorithm can be effectively applied in the polarization-sensitive array, which may and deepen the null depth by 15 to 25dB and considerably enhance the anti-jamming performance of the spatial and polarization filtering.
