Abstract

The invention relates to the technical field of radio frequency signal polarization characteristic control and regeneration, and discloses a method and device for generating multi-polarization radio frequency signals. The method includes the steps that input radio frequency signals are equally divided through a power divider, the amplitude and the phase attributes of signals of two polarization attribute radio frequency signal circuits correspondingly connected with the output end of the power divider are controlled, two paths of polarization attribute radio frequency signals are orthogonally synthesized on a double-ridge conical-horn antenna to radiate the radio frequency signals with multi-polarization attributes, and then the goal of rapidly controlling and adjusting the polarization attributes of the radio frequency signals is achieved. According to the device, the equal division output end of the power divider is connected with the double-ridge conical-horn antenna through the radio frequency signal circuits, wherein each radio frequency signal circuit is composed of a digital attenuator and a digital phase shifter. By the adoption of the method and device, the polarization attributes of the radio frequency signals can be rapidly changed in real time, or an upper computer sends control commands to rapidly change the polarization attributes of the radio frequency signals, and real-time control over the polarization attributes of the radio frequency signals is achieved. The device is simple in structure, and easy and convenient to control.
