Description
technical field [0001] The invention relates to the field of radio frequency signal synthesis, in particular to a vector synthesizer with phase compensation. Background technique [0002] In communication direction finding technology, vector synthesizer is widely used in single channel correlation interferometer communication direction finding system. The essence of the single-channel correlation interferometer communication direction finding system is to use the phase relationship generated by the radio signal in the antenna element to determine the orientation of the radio signal. The phase of a signal refers to the phase of this signal relative to another signal of the same frequency ; In the direction finding process, the vector synthesizer converts the phase relationship received between the antennas into an amplitude relationship, and then converts it into an intermediate frequency signal for A / D computer processing through the receiver, and calculates the amplitude re...
