为提高反辐射无人机对目标雷达的搜索压制效率,文中以反辐射无人机导引头具有视场约束的特点为切入点进行搜索航路规划。基于分层规划思想,提出“视场覆盖率”这一搜索航路规划代价指标,利用改进人工势场法进行反辐射无人机的搜索航路规划。仿真结果表明,该方法规划出的航路不仅安全、可飞,而且大大提高了导引头对目标雷达的搜索压制效率,有助于提高反辐射无人机的作战效能。

In order to improve the search and suppression efficiency of the anti-radiation UAV to the target radar, this paper took the view field constraint of the seeker of the UAV as the starting point to plan the search route. Based on the idea of hierarchical planning, the cost index of search route planning, “field coverage rate”, was proposed, and the improved artificial potential field method was used to carry out the search route planning of anti-radiation UAV. Simulation results show that the route planned by this method is not only safe and flight-able, but also greatly improves the search and suppression efficiency of seeker to target radar, which is helpful to improve the combat effectiveness of anti-radiation UAV.
