水下航行器协调控制技术中航行器跟踪避障控制(Underwater vehicle coordinated control technology in the aircraft track obstacle avoidance control )

说明：  matlab编写的FDTD（时域有限差分法）程序，可以实现完整天线方向图和反射系数的计算，以贴片天线为例，对比了编写程序的反射系数与方向图和HFSS计算的反射系数与方向图，具有一致性。(FDTD (finite difference time domain) program compiled by Matlab can realize the calculation of complete antenna pattern and reflection coefficient. Taking patch antenna as an example, the reflection coefficient and pattern calculated by the program and HFSS are compared, which are consistent.)
