基于频率分集阵列的复杂环境定点干扰方法

Fixed-point interference method based on frequency diversity array in complex environment

为了解决传统点源干扰枪及相控阵雷达对无人机干扰时会对同方位的所有设备产生干扰的问题,在频控阵的基础上提出了一种基于频率分集阵列的复杂环境定点干扰方法。利用频控阵的距离-角度依赖性实现对目标的定点干扰,并针对复杂环境下频控阵干扰时其周期主瓣会对周边设备产生影响的问题,设计了一种优化规避模型。仿真结果表明,该定点干扰方法可以对指定目标进行干扰,同时降低其余目标处功率,相较于传统方法具有更好的灵活性。

In order to solve the problem that the traditional point source jammer and phased array radar interfere with all equipments in the same direction when the UAV interferes with the UAV, a complex environment fixed-point interference based on frequency diversity array is proposed based on the frequency control array. Design method. The fixed-point interference to the target is realized by the distance-angle dependence of the frequency control array, and an optimization avoidance model is designed for the problem that the periodic main lobe affects the peripheral equipment in the frequency-frequency array interference in complex environment. The simulation results show that the fixed-point interference method can reduce the power of the remaining targets while interfering with the specified target, which has better flexibility than the traditional method.
