摘要: The focusing resolution is very important perfor- mance for ultra wideband (UWB) imaging system. In this pa- per, the accuracy of with time-reversal (TR) electromagnetic (EM) pulse propagation analyzed. TR EM done via numerical simulation finite difference time domain (FDTD) method. modulated Gaussian used as UWB pulse. directional error at specific locations shown. results are discussed in conclusion.
