Terrain following and terrain avoidance (TF/TA) flight is an effective method to penetrate enemy' s airspace. Modern air-crafts are equipped by Low Altitude Navigation Pod which can help pilots to flight for TF/TA. But, the flight test is very dangerous, costly and time - consuming. In this article, the TF/TA real - time simulator is introduced including its structures and key technologies. Based on this platform many simulation test of TF/TA are done which improved the navigation algorithms and reduce the flight - test risk, cost and time effectively.%为了低空飞行突破敌人防线,现代先进飞机配有低空突防导航设备导引飞行员实现贴地飞行和低空障碍回避；然而,低空突防导航设备的试飞试验不仅风险极高,而且代价高昂、试验周期长；文中构建了低空突防导航实时仿真测试系统,给出了仿真测试系统的结构设计、关键技术设计,并基于此系统对突防导航算法进行充分仿真测试,大大减少了实际试飞验证的次数,从而降低了试飞风险和试飞成本.
