In July 2019, the U.S. Marines in the Strait of Hormuz successfully used a new portable jamming system (LMADIS) to shoot down an Iranian drone.cell phone jammer The incident occurred near the U.S. Navy's amphibious assault ship Boxer. When the drone was less than a mile away from the ship, the Marines forced it to fall into the sea by jamming its signals, demonstrating the effectiveness of modern military technology in dealing with drone threats.signal jammer

　　LMADIS system introduction

　　LMADIS (Light Marine Air Defense Integrated System) is a counter-weapon against drones. It consists of two Polaris MRZR all-terrain vehicles, one as a command vehicle and the other as a GPS jammer . The system combines the RPS-42 tactical air surveillance radar, a small electro-optical/infrared camera, and the Skyview RF detection system to quickly identify and intercept potential threats by monitoring the communication between the drone and its operator.Wifi jammer

　　Operational process

　　The workflow of LMADIS is as follows: First, the RPS-42 radar detects the presence of the drone; then, the Skyview system monitors the signal of the drone operator. drone jammer When the target is determined to be an enemy drone, the Marine Corps will mobilize the MODi jammer to block the drone's control signal, causing it to lose control and eventually crash.GSM jammer This operation is not only fast and effective, but also able to provide timely response in a complex battlefield environment.

　　Types and threats of drones

　　The Iranian drone shot down in this incident is suspected to belong to the Mohajer series. The Pentagon said that the drone is a fixed-wing unmanned aerial system (UAS) with high combat capabilities. Although the US military confirmed that the drone was shot down, Iran denied this statement, claiming that the drone was not attacked.

　　In response to the increasingly complex drone threats, the Marine Corps plans to integrate more technologies into the LMADIS system, including kinetic weapons and laser weapons. This will not only enhance the Marine Corps' survivability on the battlefield, but also provide strong technical support for future drone confrontations. With the continuous evolution of drone technology, establishing a multi-level air defense system has become an important task in the development of military forces.
