The system is comprised of two vehicles — one a “command node,” and the other a “sensor node.” The vehicles are outfitted with radar sensors, cameras, and radio frequency detectors and signal jammer. Once the crew is able to detect a threat, they use the jammer to disrupt the signals from the drone. While the system has been tested out on land by ground forces, Military.com reports that the Navy and Marines began testing the system on ships earlier this year.
The Drive/WarZone published an article describing an anti-drone system known as the Light Marine Air Defense Integrated System (LMADIS). The system consists of a RADA RPS-42 short range, S-band, hemispheric, AESA radar mounted on an MRZR dune buggy. On top of the radar unit is a gyro-stabilized CM202 multi-sensor optical ball that provides positive visual identification of targets. (2) The systems apparently operate in pairs. When a target is designated, the targeting data can be fed to various systems such as a Modi 5g jammer which is a backpack signal jammer. (3) Theoretically, the targeting data could be fed to a ship’s hard-kill defensive systems but it is unknown (and probably unlikely) that this was possible, in this case. It appears that the Modi jammer was used to disrupt the ground control signal to the Iranian drone thereby causing it to crash.
Jamming mobile phones is like jamming any other type of radio communication.A mobile phone communicates with its service network through a base station. As the phone user drives down the street, the signal switches from one base station to another.Different communication systems use different frequencies so that everyone is at peace.The NERO F5 is developed and manufactured by the French Company MC2 Technologies. It is a microwave jammer capable of disrupting and neutralizing all communication protocols used by drones. The product is based on a portable rifle offering great flexibility for operators in terms of detection, tracking and neutralization.
LMADIS engagement procedure goes something like this: the RPS-42 detects the drone on radar, or alternately Skyview detects the back-and-forth radio signals between the drone operators and the drone itself. Next, the electro-optical/infrared camera is trained on the incoming drone to make a positive identification as friendly or hostile. If hostile, the Marines aim the MODi jammer at the drone and prevent the drone operators’ radio commands from reaching it. Gravity takes care of the rest.
