Radar Target Imaging Using Time-Reversed Processing

摘要

This thesis investigates and demonstrates the workability of the time-reversed process for radar imaging applications, particularly, for bi- static or multi-static radars. One benefit of the time-reversed process is its ability to reduce the calculation to determine the targets' shape. The finite- difference-time-domain (FDTD) method is used to demonstrate the time-reversed process. Following an overview and description of the principles of the time- reversed process, the FDTD method is applied to the wave equation and the time reversed-process in 2-D space.
