【摘要】：针对飞行器未知环境下自主地形跟随问题,提出了基于前视序列图像天地线的地形跟随方法,并利用适应角法设计了制导律,该方法利用被动成像实时探测飞行前方地形信息,降低了对数字地图保障及高精度导航的需求。六自由度非线性数学仿真结果表明:基于前视序列图像天地线的方法较传统基于数字地图的方法,地形跟随平均离地高度可降低35%以上,可大幅提高飞行器超低空突防性能。
[Abstract]:In order to solve the problem of autonomous terrain following in unknown environment, a terrain following method based on forward view sequence images is proposed, and a guidance law is designed by using adaptive angle method. This method uses passive imaging to detect terrain information in front of flight in real time. The requirement of digital map guarantee and high precision navigation is reduced. The nonlinear mathematical simulation results of six degrees of freedom show that the terrain following average altitude can be reduced by more than 35% compared with the traditional method based on digital map, which can greatly improve the penetration performance of the aircraft at very low altitude.
