This paper proposes a solution based on time-domain scale transformation to solve the mismatch problem between the time reversal signal frequency and the time reversal mirror transmitter operating frequency band. The spectrum shift in the frequency domain is achieved by stretching and compressing the received signal in the time domain. This method is suitable for monochromatic radiation signals and broadband signals, and the relative bandwidth remains unchanged after moving. Through simulation verification, the signal can also form focus at the radiation source position after performing scale transformation.
