A Method for Polarization Estimation and Direction-Finding Based on Virtual Polarization Synthesis Using 1-Bit Time-Modulated Arrays

This paper presents a method for polarization estimating and direction-finding of incident signals using a singlechannel one-bit time-modulated array. The proposed approach achieves polarization synthesis for a dual-polarized antenna with just one sampling channel. By extracting harmonic signals and matching polarization, it provides robust angle and polarization estimation under any polarization of the incident signal. Simulations confirm the effectiveness of the proposed method.
