Description

Unmanned aerial vehicle near field test fixture

Technical Field

The utility model mainly relates to the technical field of electromagnetic noise near-field injection, in particular to an unmanned aerial vehicle near-field test fixture.

Background

In general, in all possible potential military and commercial demand backgrounds of high-power microwaves, a fixed-emission antenna is utilized to radiate high-power electromagnetic pulse signals to a target electronic system, the high-power electromagnetic pulse signals enter the system through coupling of a front door or a back door, and a sensitive circuit is reached to generate disturbing and even damaging effects, and the high-power electromagnetic pulse signal generator has the characteristics of non-deadly, all weather and high efficiency and cost.

The main modes of microwave attack unmanned aerial vehicle are as follows:

1) The interference blocking is mainly realized by techniques such as signal interference, acoustic interference and the like.

2) The monitoring control is realized mainly by hijacking radio control and the like.

3) Direct destruction of classes, including use of laser weapons, countering with drones, etc.

The first mode can generate a 2.4GHz/5.8GHz frequency band unmanned aerial vehicle flight control interference signal and a satellite positioning interference signal, and the unmanned aerial vehicle flight control instruction and satellite positioning information are lost by performing blocking interference on an uplink flight control channel and a satellite positioning channel of the unmanned aerial vehicle, so that the unmanned aerial vehicle cannot normally fly, and a control effect of returning, landing and falling can be generated according to different designs of the unmanned aerial vehicle.

The second mode realizes unmanned aerial vehicle return voyage, landing or flying in a contracted range through hijacking radio control and the like, and cannot exceed the appointed range, such as electronic fence and the like.

The third mode utilizes a fixed-emission antenna of the microwave emitter 11 to emit high-power microwave electromagnetic pulse signals to the target unmanned aerial vehicle 10, and the high-power microwave electromagnetic pulse signals enter an internal system of the unmanned aerial vehicle through electromagnetic coupling, so that the influence sensitive circuits generate disturbing, direct knockdown and even damage results, as shown in fig. 1.

However, the third type of far-field microwave electromagnetic interference and electromagnetic pulse interference is difficult to determine which part of hardware and software inside the unmanned aerial vehicle 10 is caused by the microwave or the unmanned aerial vehicle 10 cannot work normally due to communication because of the long-distance attack. At the same time, the mechanism of failure caused by electric field or magnetic field cannot be clearly disturbed. The intrusion path of the microwave interference is not confirmed.

In order to determine the mechanism that the unmanned aerial vehicle cannot work normally due to electromagnetic interference, the information such as the sensitive part, the sensitive direction, the sensitive property, the noise invasion path and the like of the unmanned aerial vehicle needs to be confirmed in the mode of injecting electromagnetic interference into the near-field probe for the unmanned aerial vehicle, so that the property and the mechanism that software, communication and hardware of the unmanned aerial vehicle are interfered are determined.

Fig. 2 is a schematic diagram of an experimental scenario of near field injection unmanned aerial vehicle using a near field probe, a noise generator, and a power amplifier.

When the interference signal is injected in the near field, the experimenter needs to hold the near field probe 21 or the noise signal generator 23 to contact the unmanned aerial vehicle 10 in the flight, and the interference signal is decoupled from different parts and different directions of the unmanned aerial vehicle 10, so that the effect of the interference unmanned aerial vehicle is achieved. When the unmanned aerial vehicle flies abnormally, falls and even is directly damaged, the sensitive part of the unmanned aerial vehicle can be confirmed, and whether the unmanned aerial vehicle is sensitive to an electric field or a magnetic field can be judged according to different types of the near-field probes 21. Meanwhile, the far-field disturbed threshold and the sensitive frequency of the unmanned aerial vehicle 10 can be converted according to the output power of the power amplifier 22, the noise frequency emitted by the noise signal generator 23 and the distance of the near-field injection probe 21.

When carrying out above-mentioned noise injection test, the experimenter must hold near field probe 21 to and unmanned aerial vehicle 10 carries out noise injection in the normal flight in-process, however unmanned aerial vehicle has infrared obstacle avoidance function, can be detected infrared ray when the experimenter is close to unmanned aerial vehicle 10, and unmanned aerial vehicle opportunity is automatic risen, makes unmanned aerial vehicle keep away from the experimenter, leads to near field probe not reaching unmanned aerial vehicle, leads to unable near field injection interference noise.

In order to smoothly finish the near field injection of interference noise of the unmanned aerial vehicle, a near field interference injection test fixture needs to be developed, infrared obstacle avoidance detection of the unmanned aerial vehicle can be avoided, and near field injection of interference noise from different positions and different directions of the unmanned aerial vehicle is realized.
