基于小采样的地形匹配区适应性技术研究

Adaptive technology Study:of Terrain Matching Region Based on Small Sampling

地形匹配在军事和民用领域都具有广泛的应用,特别是其作为巡航导弹等武器系统的辅助导航方式,在战前必须对其进行航迹规划。而航迹规划中必须选择那些具有较强适应性的地形区域,才能保证匹配制导的可靠性和精度。为此,本文就地形匹配区的适应性进行了讨论,通过分析影响地形匹配性能的主要地形参数,提出了选择地形匹配区的基本原则,不同于其它原则之处,本文以小采样技术来验证区域的适配性,从而确定区域适配性强弱,取得了良好效果。

As all know, terrain matching technique is an important assistant navigation techniques. Before war, track programming is necessary. In order to ensure the reliability and precision of matching guidance, the regions which have good adaptabilities should be chosen as candidate matching regions. So the paper mainly discusses the adaptability of terrain matching regions. After the main terrain parameters influencing terrain matching performances have been analyzed, the basic rules selecting terrain matching regions are presented. Unlike other general rules, here small sampling technology is adopted to verify regional matching adaptability, and thereby whether strong or weak adaptability is determined. Experiment results show good effects.
