Abstract :
Firstly, this paper introduces amplitude-phase characteristic test requirement and application of multi-channel phase coherent signal, and then puts emphasis on realizing accurate test for amplitude-phase coherence of multi-channel phase coherent signal with frequency tracking and vector error correction technology. Finally, the feasibility of this method is proved by experiment data of multi-channel receivers.
