摘　　要：该文介绍一个多算法的水下地形辅助导航系统模型,并基于此模型采用VC++搭建了系统仿真平台,在平台构建过程中主要考虑了五个因素:①反映真实的物理环境;②能很好满足实验目的;③较快的运行速度;④良好的可扩展性;⑤提供简洁的人机交互接口与结果表达。仿真平台分为8个模块以满足良好的扩展性,VC++的使用可使平台用户得到更快的计算速度和丰富简便的图形界面,系统模块中的数学模型反映了真实环境。仿真试验表明平台能够良好运行并为算法的研究提供大量试验数据。A system model of underwater Terrain - aided Navigation （TAN） is introduced in the paper, which is based on the simulation platform with Visual C ＋ ＋. Five factors are considered in its construction： the real environment similarity, all kinds of experiment demand, calculation speed, extensibility, interface and result representation. The platform is divided into 8 modules to get good extensibility. Visual C ＋ ＋ is valuable for user to get faster compuring speed and better interface. The modals are well designed to simulate real environment. The simulation results show that the platform runs efficiently and can provide a great number of experiment methods for matching algorithms.
