雷达干扰无人机典型压制干扰航路主要有跑道形和“8冶字形两种。文中分别建立了两种典型航路的数学模型,利用航路偏离代价,分别对两种典型航路的持久干扰扇面进行研究,分析了航路偏离代价与干扰距离关系、航路偏离代价与航路纵向长度关系。计算结果表明:采用“8冶字形航路飞行的雷达干扰无人机航路偏离代价较小,对雷达形成的持久干扰扇面大于采用跑道形航路飞行的雷达干扰无人机,并求解给出了采用“8冶字形航路飞行的雷达干扰无人机最佳航路纵向长度与干扰距离关系。

Runway-shaped and “8”-shaped paths are two typical oppressive jamming paths of radar jamming UAV. Models of two typical paths are established first. By using path deviate cost, the enduring jamming coverings of fan are researched respectively.The connections between the path deviate cost and jamming distance, path longitudinal length are analyzed. The results show that the radar jamming UAV which adopts the “8”-shaped path gets a much smaller path deviate cost, which means that the radar jamming UAV gets a much bigger jamming covering of fan than the other one. The connection between optimal path longitudinal length and jamming distance is presented when oppressive radar jamming UAV adopts the “8”-shaped path.
