Research on Multi Station Power Synthesis Basedon Time Reversal Mirror

Abstract

In the process of transmission, electromagnetic waves will be affected by terrain and ground objects, resulting in reflection, diffraction, and scattering. The receiving end receives signals with different paths superimposed on each other. In this way, the superposition of signals from the same source and different paths will strengthen or attenuate the energy of the signal. The emergence of time reversal technology turns the unfavorable factors of multipath effects into favorable factors, and makes full use of multipath components for superposition, so as to achieve energy focusing Effect. Based on the basic principle of time-reversal mirror and the propagation environment of multipath delay channel, this paper studies the application of time-reversal mirror technology in multi-station power combining. The basic theory of time-reversal mirror application is studied and discussed, and the signal power enhancement characteristics of time-reversal mirror in array signals are deduced, which can effectively Increase the signal synthesis power, thereby improving the signal quality of the multipath channel.
