Fighting small drones. Part of 2
Depending on the customer’s wish, ReDrone from Eibst Systems is supplied in two configurations - only a sensor or a sensor plus an executive component
Last year, Rafael announced the addition of a direct-kill component in the form of a laser capable of neutralizing a drone at a distance of 2,5 km; depending on the choice of the customer, the output power varies from 2 to 10 kW. At the maximum distance, the required hold time on the target is about 10 seconds, while the shorter the distance, the less time is needed to hold on the target. This executive component will be available to customers at the end of 2018. At the end of 2016, Elbit Systems introduced the ReDrone system available in different configurations: portable, portable and portable. The Level 1 variant is based solely on a passive electromagnetic detection, identification and location system. 360° field of view system emits only when needed to disrupt operation drone. The Level 2 variant, integrated with radar and optoelectronics, increases the range to 3-4 km.
The IMI Systems Red Sky 2 system closes the 360 ° sector due to continuous rotation. It includes a camera with a continuous zoom, an infrared tracking device with a horizontal field of view from 2,2 ° to 27 °, operating in the 3-5 μm range, and a portable X-band radar. The mass of the system is 30 kg, at the same time it can track up to 100 targets, the detection distance of small-sized UAVs is 6 km. The system is complemented by two jamming devices, a broadband omnidirectional high-power system with an output power of 400 W and a separate multi-directional jamming device capable of detecting and creating interference at a distance of 600 meters, as well as a control unit. IMI Systems has announced the sale of "several" Red Sky 2 systems to Thailand in December 2017. A month earlier, IAI-Elta announced a contract worth 39 million dollars for its DroneGuard system, which was first shown in February 2016. It is based on the ELM-2026D, ELM-2026B and ELM-2026BF three-coordinate radars with different detection ranges, respectively 10, 15 and 20 km. The radar is complemented by optocoupler devices and special systems of active electronic suppression, guaranteeing the violation of the flight of the drone.
At the IDEF 2017 exhibition, the Turkish company Aselsan presented various anti-thrust systems, among which was a portable gun Ihasavar
Short-range countermeasures
Many companies are engaged in the development and production of short-range anti-thrust systems. The French ITHPP Alcen, for example, developed the Drone Sniper, a 1,9 kg module that mounts under the assault rifle barrel like a grenade launcher. It can drown out GLONASS (L1) signals, Wi-Fi 2,4 and 5.8 GHz frequencies, the total radiated power is 5 W. A directional antenna ensures effective jamming at a distance from 500 to 1000 meters, the lithium-ion battery provides a working time up to 1,5 hours.
The British company Steel Rock offers its solutions to the NightFighter series. NightFighter Digital uses white noise technology against all targets and features custom multi-band helical and flat panel antenna arrays. The jamming device and battery are housed in a dorsal pack, while the directional antenna is attached to the AR-15 rifle via a rail that the customer can also mount a scope of their choice. The NightFighter Pro system operates on five frequency bands covering most of the operating frequencies drones. The output power and directivity for each frequency range can be adjusted separately, the physical dimensions are similar to those of the junior model.
At IDEF 2017, Aselsan unveiled its Ihasavar radio frequency jamming system with a radio frequency output of 50 W, operating in two 400-3000 MHz and 5700-5900 MHz bands. The system, equipped with a directional antenna with a high directional ratio, can operate from a lithium-ion battery for up to one and a half hours. In Turkey itself, 25 systems were installed, mainly for military customers, five more systems were supplied by Turkish Airlines to protect Istanbul Ataturk and Sabiha Gokcen airports to fight drones that could disrupt their operations. In the coming months, Aselsan is expecting an order from the Turkish military for another 200-500 system after positive feedback from military tests.
As for the export market, at the end of 2017, Aselsan delivered approximately 50 systems to a Ihasavar customer from the Middle East, who deployed them in his land forces, while the company expects several more contracts for the supply of 2018-10 systems in 20. At IDEF 2017, Aselsan also unveiled its Meerkat pocket radio frequency receiver operating in the 20-6000 MHz band, originally intended as a warning device for special forces. The company from Ankara is developing an algorithm capable of detecting and classifying the radio channels of UAVs, giving the operator an approximate direction (in the form of an hour hand) to the desired drone. This will significantly improve the efficiency of the Meerkat system, while maintaining it portable. Technical demonstrations of Meerkat were successfully held, and Aselsan is currently in the process of certification, hoping that the new system will enter the market by the end of 2018.
The Danish company MyDefence has developed numerous radio frequency sensors, including the Wolfpack system weighing 5 kg, operating in the frequency range from 70 MHz to 6 GHz
Sensors and actuators
Numerous European companies supply sensors or actuating systems. The French Cerbair offers mobile and stationary sensor kits, the first one is mounted on a retractable mast, and the second one on the infrastructure facility itself. Both systems are built on the same modules: the DW-OP-01 optical sensor with a 92 ° field of view and 100 detection distances at night and 150 meters during the day, the DW-RF-01 radio frequency sensor with a viewing sector in azimuth 90 °, operating in 2,4 and 6,875 GHz bands, single or dual band antennas are also available for the system. The sensors are connected to a computer using the Dronewatch software, which allows you to detect, track and identify all types of civilian drones.

German Aaronia also offers its Aartos radio frequency system, which includes a three-coordinate radar Iso-LOG, a portable or stationary spectrum analyzer in real time and a special software extension for it. Depending on the antenna and analyzer, the range varies from 500 meters to 7 km.
The Danish company MyDefence offers a full range of systems, ranging from sensors to actuators. For example, two wearable personal drone approach warning systems are offered: the Wingman 100 for the police and the enhanced Wingman 101 for the special forces. Both systems weighing less than 500 grams operate in the 70 MHz-6 GHz band and are equipped with a semi-directional antenna (an omnidirectional antenna is available, providing a circular viewing sector). The Wingman 100 and 101 models are distinguished by their power sources and operating temperatures. Through continuous scanning, the Wingman system can detect communication channels, giving audible, vibratory or visual warnings.
The watchdog radio frequency system of the same company is suitable for fixed installation. It is capable of detecting signals in the 70 MHz-6 GHz band, the detection distances exceed 2 km in the sector in azimuth 60 °; several sensors can be networked to increase range and accuracy. A small and lightweight 515 gram sensor can be easily integrated into a vehicle. The larger and heavier Wolfpack 5 kg sensor has the same range, operates at the same frequencies, but closes all 360 ° in azimuth. The Danish company is also developing a portable (deployed by one person) Eagle X-band radar with a mass of just 23 kg and a detection range of 1,5 km, capable of rotating on 360 °. In order to integrate its sensors, MyDefence has developed an Iris warning and control system, which is capable of adopting sensors from other manufacturers due to its own software package.
British DroneDefence in 2017 year established its SkyFence system to protect the prison of Guernsey. A typical system operating on 2,4 and 5,8 GHz frequencies consists of six radio frequency receivers with a 60 ° review sector; it can be connected to control units, which in turn are connected to the command center via a local network. This allows for the detection of a drone to switch to the barrier mode to counter the threat. The company also offers the Dynopis EYOOMR directional jamming device - a portable 10 kg system operating at the same frequencies as SkyFence, which can disrupt the transmission of video and satellite communications signals within a radius of one kilometer.
The company also developed a security system for the last frontier Net Gun X1, mainly intended for law enforcement. Setemet throws a square network 3x3 meters to a distance of 5-10 meters or a round network with a radius of 1,5 meters to a distance 15 meters, creating a protective barrier in the first case or grabbing a drone in the second.
