A fast echo construction method in through-the-wall application: Simulation and analysis

The fast and effective construction of the echo has great significance in TWI application, especially in imaging and detection algorithm validation and further process. The current echo construction methods are usually complex and difficult to realize. As a result, they are not conveniently used in projects. By conducting a deep analysis of the wall's characteristics and the signal transmission models, a fast echo construction method is proposed in this paper. The method is efficient and easy to realize, with the essential characteristics of the TWI being kept, which can perfectly meet the needs of algorithm validation and project use. The simulation and theoretical analysis validate this method.
