This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a two-dimensional Cartesian space lattice comprised of uniform square grid cells. To illustrate the algorithm, a 6-cm-diameter metal cylindric

用于时频分析算法，空间目标识别，采用PM算法，采用波束成形技术的BER计算。- For time-frequency analysis algorithm, Space target recognition algorithm using PM, By applying the beam forming technology of BE.
