The invention discloses an unmanned aerial vehicle near-field test tool, which is used in combination with a near-field probe, and comprises a telescopic supporting unit, a near-field test unit and a near-field test unit, the clamping device is arranged at the end part of the telescopic supporting unit and is used for clamping the near-field probe; and the control unit is arranged in the supporting unit and is used for controlling noise injection of the near-field probe and/or polarity switching of noise injection. According to the invention, near-field electromagnetic noise interference injection can be carried out when the unmanned aerial vehicle flies normally, a fault phenomenon when a far field is attacked by microwaves is simulated, convenience is provided for further analysis of a disturbed mechanism of the unmanned aerial vehicle, the problem that the unmanned aerial vehicle cannot approach due to an infrared obstacle avoidance function during near-field test of the unmanned aerial vehicle is solved, and the reliability of the unmanned aerial vehicle is improved. Key information is provided for improving the electromagnetic compatibility design of the unmanned aerial vehicle, and a threshold value judgment means for determining the disturbed unmanned aerial vehicle in a near-field electromagnetic noise injection mode is provided.

    本发明揭示了一种无人机近场测试工装,与近场探头结合使用,所述测试工装包括:可伸缩支撑单元;夹持装置,设置于所述可伸缩支撑单元的端部,用以夹持所述近场探头;操控单元,设置于所述支撑单元内,用以控制所述近场探头的噪声注入和/或噪声注入的极性切换。本发明解决了可以在无人机正常飞行时进行“近场”注入电磁噪声干扰,模拟远场受到微波攻击时的故障现象,为进一步分析无人机受扰的机理分析提供便利,同时也解决了无人机近场测试时红外避障功能带来的无法靠近问题,为改进无人机电磁兼容设计提供关键信息,提供了用近场电磁噪声注入的方式来明确无人机受扰的阈值评判手段。
