摘要: 基于无人机GPS接收机干扰容限，分析了GPS超宽谱强电磁脉冲效应机理，开展了高重复频率超宽谱电磁脉冲干扰机对典型微型无人机的效应试验，测试分析了在不同位置、不同高度、不同状态、不同飞行模式下无人机GPS接收机的高重复频率超宽谱电磁脉冲干扰效应。试验结果表明，高重复频率超宽谱电磁脉冲对无人机GPS、图传系统、下视传感器均有不同程度的干扰作用，导致无人机无法正常起飞、失控等异常现象，验证了高重复频率超宽谱电磁脉冲干扰GPS接收机的可行性。Abstract: Based on the interference tolerance of UAV GPS receiver, this paper analyzes the mechanism of GPS ultra-wide spectrum strong electromagnetic pulse effect. It presents the effect test of high-repetition ultra-wide spectrum electromagnetic pulse jammer on typical micro-UAV and analyses high-repetition and ultra-wide spectrum electromagnetic pulse interference effects of UAV GPS receivers in different positions, different heights, different states, and different flight modes. The test results show that the high-frequency ultra-wide-spectrum electromagnetic pulse has different degrees of interference on the GPS, the image transmission system and the lower-view sensor of the UAV, and the interference can be within a certain range by interfering with the GPS receiver of the UAV. The interference can cause drone's failure to take off normally, even make the UAV out of control during the flight process. It is verified that the high-repetition ultra-wide spectrum electromagnetic pulse will cause interference to the GPS receiver, making the GPS unable to work.
