Abstract
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 targetsgas 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. The FDTD numerical model is developed and used for producing fundamental examples on conducting targets. The examples reveal that the time-reversed process can be employed for radar imaging within certain constraints. Finally, conclusions regarding the time-reversed-process are presented and recommendations for future research are provided.
