Definitions
- the present invention relates to a system for incapacitating or rendering inoperative intelligent electronics provided with weak or non-existent electromagnetic protection (ie absence of electromagnetic shielding) of at least one carrier such as a drone (steering wheel, wheeling or seagoing) , a mobile phone, a camera, or any other electronic system.
- Smart electronics means electronics that allow you to acquire, store and communicate information with surrounding systems.
- An object of the invention is to overcome the problems mentioned above, and in particular to improve the efficiency of decommissioning carriers. It is proposed, according to one aspect of the invention, a system for incapacitating electronics devoid of electromagnetic shielding of at least one carrier, by backdoor, comprising:
- a device for transmitting an electromagnetic signal of variable frequency and amplitude comprising:
- the system tackles the on-board electronics of the wearer by taking advantage of flaws in the inertial sensors, engine controls, microcontroller, memories, etc.
- the system uses the principle of vulnerability by backdoor or "backdoor" in English language, that is to say without going through the conventional reception channel. For this, a high power electromagnetic wave form generating a large electric field several hundred meters away creates false detections and interpretations by the wearer, causing loss of control by its internal processor.
- Such a system is based on transportable technology that can be operated with a vehicle without major modifications.
- the amplification source makes it possible to provide a very high peak power necessary for the disturbance of the electronics. Peak power is understood to mean the maximum power of a system.
- the waveform is very important, because it allows these variations in amplitude and frequency to cause confusion in the electronics which result in interpretation errors of the microcontroller of the electronics on board the target carrier (s).
- the generation device is configured to transmit a signal of variable amplitude and variable frequency.
- the signal is generated by a single source which can be digital.
- Digital generation facilitates system programming.
- the generation device comprises a plurality of generators configured to each generate a signal of variable amplitude and respective constant frequency.
- the amplification device comprises a first amplification factor amplifier element between 30dB and 40dB with a power of 1W to 10W and a second amplification factor amplifier element between 40dB and 50dB with a power greater than or equal to 10 kWatts, for example from 10kW to 100kW.
- the first amplifier element comprises at least one solid state amplifier.
- a solid-state amplifier is used, the technology of which is available and robust for this level of power, and therefore of simplified production and of limited cost.
- the second amplifier element comprises at least one microwave tube.
- the microwave tube allows to obtain a peak power much higher than that provided by a solid state amplifier.
- the broadcasting device comprises at least one horn antenna.
- a horn antenna makes it possible to obtain good directivity and therefore a significant gain, which allows the system to produce a very large peak power in the desired direction while limiting the power in the other directions, thus limiting the collateral effects.
- the system comprises a reflector.
- a reflector for example of parabolic shape
- a generator comprises an RF source of low power less than 10 dBm.
- the generation device (2) comprises at least one reprogrammable silicon integrated circuit or a processor specialized in signal processing to generate the signal in the form of a baseband wave of the continuous at a frequency below 100 MHz, transposed to the frequency of use between 6 GHz and 18 GHz, which excludes interference because all the link frequencies are ⁇ 6 GHz, and includes a frequency mixer and a synthesizer.
- baseband of the continuous at 100 MHz signals whose frequency can vary between 0Hz and 100MHz. When the signal frequency is zero, its amplitude as a function of time is constant.
- the generation device is configured to generate a signal of variable amplitude, and of variable frequency, of repetition frequency between 10Hz and 1 MHz, of work cycle between 5% and 15 %, and frequency sweep between 1 MHz and 50 MHz.
- the repetition frequency is the number of RF or microwave pulses transmitted each second by the generation device, and the work cycle means, for a periodic phenomenon, the ratio of the duration of the phenomenon over a period and the duration of this same period, in this case the generation of the signal.
- the system comprises a battery.
- the device can easily be moved, for example in a vehicle. It can thus be transported and easily deployed in a few minutes on the various sites of use during specific and seasonal events (Gathering, Sports competitions, movement of personalities %)
- the system is configured to incapacitate electronics from a drone.
- the system makes it possible to paralyze it in its action, by rendering it inoperative, for example in the event of drone attack on a sensitive place.
- the system is configured to disable electronics from a mobile phone, a camera, a camera, or a data transmission system.
- the system comprises a control card configured to manage the system, by receiving azimuth and site information from a detected carrier and by controlling the emission of the disturbance signal, by transmitting the information to the generation device and to the positioning device.
- Figure 1 schematically illustrates a system for incapacitating or rendering inoperative an electronics devoid of electromagnetic shielding of a carrier, according to one aspect of the invention
- Figure 2 schematically illustrates an amplification device comprising a first amplifier element and a second amplifier element, according to one aspect of the invention.

- the system therefore emits a wave or signal of microwave type frequency typically between 6 and 18 GHz, and radiated power typically between 10 and 100 MW.
- the generation device 2 has a preponderant role for the efficiency of the system, by producing the waveform at variable frequency and amplitude to create false detection and interpretation in the on-board electronics of the carrier (s). This waveform is modulated in amplitude and frequency.
- the power source 6 can be a battery, which makes the system easily transportable, for example to embark on a light vehicle, and an all terrain vehicle.
- An optional control card 6 can be added to manage the system, receiving the azimuth and site information from a detected carrier, for example by an external detector, and controlling the emission of the disturbance signal. It transmits this information to the generation 2 device and to the positioning device 5.
- the system can be used in manual mode or connected to an external control system.
- FIG. 2 schematically represents an embodiment in which the amplification device 3 comprising a first amplifier element 3a with an amplification factor of between 30 dB and 40 dB for a power supplied from 1 to 10 watts and a second amplifier element 3b with an amplification factor of between 40 dB and 50 dB for a peak power supplied greater than or equal to 10 kWatts, for example between 10 and 100 kW.
- the amplification device 3 comprises a first amplifier element 3a comprising at least one solid-state amplifier or SSPA for acronym for "Solid-State Power Amplifier" in English, and a second element amplifier 3b comprising for example at least one microwave tube.

- the positioning device 5 in elevation and in azimuth such as a positioning device used for positioning a turret of a small caliber gun or a positioning device for a satellite antenna, can ensure 360 ° Azimuth positioning and 60 ° site positioning.
- the positioning device 5 ensures the positioning given to the antenna, from data supplied by an external detection device. It can be manual or controlled by the detection system.
- FIG. 3 schematically illustrates an embodiment in which the generation device comprises a plurality of generators, in this case three, each configured to generate a signal of variable amplitude and respectively of constant frequency, according to one aspect of the invention.
