Establishment of Single-Frequency Rectangular Pulse Signal with Time Reversal Mirror Simulation

This document discusses the process of establishing a single-frequency rectangular pulse signal and performing time reversal mirror simulation. We will also calculate the energy gain of the signal after time reversal. This procedure helps understand key concepts and techniques in signal processing. The implementation involves generating a rectangular pulse using MATLAB's pulse shaping functions or custom code with specific amplitude, duration, and frequency parameters, then applying time reversal transformation through array manipulation techniques. The simulation demonstrates how time reversal processing can focus signal energy in both temporal and spatial domains. Finally, we compute the energy gain by comparing the signal energy before and after reversal using numerical integration methods. Through detailed examination of these steps, users can better grasp fundamental principles of signal processing, providing greater flexibility and creativity for future work in related fields.
