Theoretical Calculation of Carrying Load UAV Based on Radar Countermeasure Principle

采用数值计算方法,研究了无人机携带电子干扰载荷对水面舰艇雷达产生干扰效果时,电子干扰载荷功率与干扰距离的函数关系,并分析了无人机的雷达截面积和压制系数对电子干扰载荷功率的影响。为确定无人机最佳飞行高度,研究了无人机与水面舰艇的径向距离和电子干扰载荷有干扰效果时的无人机最大飞行高度,并分析了波束宽度对雷达分辨范围的影响。研究结果可为无人机电子干扰载荷的选择和无人机编队间隔距离的设计提供理论依据。

In this paper,the numerical calculation method is used to study the functional relationship between the electronic jamming load power and jamming distance when the electronic jamming load carried by the UAV produces a jamming effect on the surface ship radar,and the influences of the radar cross-section area and suppression coefficient of the UAV on the electronic jamming load power are analyzed.To determine the optimal flight altitude of the UAV,the radial distance between the UAV and surface ship,and the maximum flight altitude of the UAV when the electronic jamming load has a jamming effect are studied.Moreover,the influence of wave velocity width on radar resolution range is analyzed.The results of this paper can provide theoretical foundations for the selection of electronic jamming load and the design of the UAV formation spacing distance.
