Abstract
AbstractThis paper mainly researches on the realization of time reversal mirror (TRM) based on the analog signal processing technology. Using chirped dispersive delay lines (CDDL) and based on Fourier transform theory, the solution for achieving time reversal (TR) waveform transformation has been concept proposed and theoretically analyzed. Furthermore, using two designed delay lines with the slope of −0.4 ns/GHz, the paper experimentally achieves time‐reversed waveform for a microwave signal with the time length of 1 ns. Compared to conventional implementation scheme systems with CDDLs, the newly suggested one is more stable with higher time‐bandwidth products and is able to process longer time duration and wider bandwidth, which provide theoretical basis for physically achieving time‐reversed systems.
