摘要

A novel wideband digital polarization synthesis method is presented here. Themethod is based on the definition of antenna polarization and both simulated andmeasured antenna patterns. A mathematical formulation is used to determine the synthesiscoefficients. Any state of polarization (elliptical, circular, and linear) can besynthesized theoretically. Here, we mainly focus on the method for synthesizing linearlypolarized antennas into circularly polarized antennas. There is no restrictionregarding the array geometry or element patterns. The method can yield pure circularlypolarized antenna patterns within the whole working band. The synthesizedcircularly polarized antennas are then used to receive circularly polarized signals. Themethod can provide more accurate polarized data for wideband solar radio observationsand other systems that require accurate polarization measurements.
