测量目标的距离是雷达的基本任务之一。无线电波在均匀介质中以固定的速度直线传播（在自由空间传播速度约等于光速 km/s）。图2-1雷达位于-Measuring the distance between the target is one of the fundamental tasks of radar. Radio waves in inhomogeneous media in a straight line to a fixed rate of propagation (the propaga

In this paper, a two-dimensional (2-D) transverse magnetic (TM) mode finite difference time domain (FDTD) method is used to simulate the indoor radio wave propagation and model the indoor ultra wideband (UWB) channel. The modulated Gaussian p
