摘要:
对传统的地形轮廓匹配(TERCOM)辅助导航算法进行了如下改进:首先在景象匹配的基础上对飞行区域作出预测; 其次利用实测高程序列和预测高程序列匹配,对飞行器进行实时定位和下一时刻的航迹预测; 最后利用递推和缩小匹配网格搜索范围等手段减少计算量. 该方法提高了地形轮廓匹配的实时性和精度,增加了飞行器超低空飞行的可靠性和机动性.
Abstract:
This paper improves the conventional terrain contour matching(TERCOM) aided navigation system algorithm as fellows: first, the region to be flown are forecasted on the basis of stereo matching; then, the matching result of the real-measured and forecast terrain height sequences is used to locate the position of aircraft and to forecast aircraft track in the next time interval; at last, by recursion and reducing the search range of matching grid, the computation burden is reduced. The method presented in this paper improves the real-time property and the precision of TERCOM, and enhances the security and maneuverability of aircraft at low altitude flight.
