Today, drones have the proficiency of spying, recording and broadcasting unlawful videos. They can also ship explosives, illegal freights and other commodities; and even assign or carry out terrorist attacks, homicides and more.
These days, security forces all over the world are facing an emerging threat via Radio-coordinated drones, flying over-crowded stadiums, reformatories and places with people in abundance. Owning the capability of eavesdropping, documenting and broadcasting illegal videos, they can also transport explosives or even commit terrorist attacks, and more.
Due to these threats, a Drone Jammer or Unmanned Aerial Vehicle (UAV) jammer was established. The drone jammer constructed for military utilization can block small to medium-sized drone in various methods.
What is drone detection?
A drone detection technology works to detect unmanned aircraft systems (UAS), or drones as they are mostly known. There are different technologies used for drone detection activity in the airspace, with each technology varying in their capabilities with respect to drone size and detection range. Drones working on RF communication can be traced utilizing RF sensors, on the other hand, others that are programmed prior via GPS to a way point, can be trailed utilizing radar detection.
Understanding the subsystems of a drone jammer!
The cohesive anti-drone jammer system comprises of the below subsystems:
a. Radar: This device uses radio energy for detecting drones. The radar produces signals-out and examines its reflection, understanding the distance (for the situated location) and direction. The Radar can identify the high-velocity miniature drones of up to 0.01 sqm Radar Cross Section. It functions in ISM, X, S Frequency Bands with a direct bandwidth of 50 MHz or more. The maximum drone detection range depends on the frequency band used, power output and the size of the drone.
b. Thermal (EO/IR) Cameras: Thermal drone detection can be a helpful tool for finding drone in a remote region. The classification is carried out utilizing a top-performance Thermal Camera. As optical cameras might not be able to recognize miniature drones flying at that high speed, a thermal camera is also utilized. The thermal cameras can either be cooled or uncooled and have diverse ranges on the basis of wavelength of IR being utilized. Furthermore, several lens alternatives ranging from 7mm up to 60mm for having unique views of the field can be opted too.
c. Direction-finding RF Sensors: An RF Sensor based drone detection works by discovering radio-links between a drone and remote-control station, detecting radio frequency (RF) signs of Wi-Fi signals. The RF sensor locates a targeted radio signal, identifies it and steps ahead with neutralization of unwanted UAV. By utilizing numerous RF Sensors, the drone operator could as well be confined, where drone swarms can be trailed and mapped instantly. In fact, few of the RF sensors are now owning direction-finding antennas unified into them so that the drones can be localized and displayed on the cohesive digital maps with the drone defense system.
d. Acoustic Drone Detection: Due to their varied construction, each drone creates unique sounds, and these can be sensed by using acoustic sensors. Acoustic sensors are created via a collection of range of microphones that can identify sounds generated by drones and evaluate direction. These sensors don’t need any direct line of sight to the object to operate accurately.
e. RF Jammers: As a soft-kill method, RF jammers utilized against control & navigation signals, neutralize drone threats in the defense systems. By transmitting stronger jamming signals, the RF remote control and navigation signals are jammed, and drones turn unmanageable by the user. With the assistance of the radar and/or various other tracking sensors in the system, jammer transmits high power RF signal in the direction of the dangers or risks and they are left un-operational for their planned mission and they either land on the field or goes back to origin.
Overall, Stratign believes that an all-embracing Drone Jamming solution is one which is cost-effective & customized.
Stratign’s anti-drone jammer system
To secure the UAV threat, Stratign’s method is based on a 4-step workflow:
- DETECT the potential threat with the finest possible probability of drone detection using Radar and RF detection.
- LOCATE the drone on a digitized map.
- IDENTIFY the potential danger as a genuine threat with the least probable deceptive-alarm rate using the EO/IR Cam and focused proprietary algorithms.
- ACT on the intimidations by raising alarms or opposing the threat with a countermeasure utilizing RF jammers.
Advantageous Features of Stratign’s Drone Jammer:
- The system can Detect, Locate, Identify, Disrupt UAVs navigation system and data links up to 1000 mt. The range can be me extended up to 3-5 km based on the necessity and size of the drone.
- An active solution capable of handling most of the commercial drones.
- An integrated RF sensor and jammer solution for instantaneous action on drone detection.
- The ability of locating direction and spot of drone utilizing various RF sensors in tandem.
- Manifold systems can be used to shield larger vulnerable regions close to public localities where civilian access is not a hassle.
In conclusion, apart from its accurate usage in the military field, this beneficial ‘Drone Jammer’ from Stratign can aid its application in the avoidance of criminal operations.
