With the widespread use of the current civilian drone market, after purchasing the civilian version of the drone, it is slightly modified and adjusted to be used in military combat, or to launch terrorist attacks through drones, so as to interfere with drones. The demand for the device also came into being. According to the cover of the application scenario, the portable drone jammer plays a very critical and necessary protection measure for the soldier's individual combat environment. So what are its specific protection functions?

In the news videos or pictures spread from the recent special military conflict between Russia and Ukraine, we can often see image recognition, target locking and attack on ground targets from the perspective of drones in the air. Targets on the ground, especially soldiers, know nothing about the reconnaissance situation of aerial drones, and they cannot predict in advance that they will become the target of attack, and can only be passively beaten. However, if the individual combat personnel on the ground carry portable drone jammers, the battlefield environment and offensive and defensive situation will be changed quickly. After the soldier only needs to turn on the portable drone jammer, the drone in the air will immediately lose important key information such as image transmission, flight control and GPS navigation and positioning.

Due to the signal interference of the portable drone jammer, the operator who loses the image transmission information will not be able to obtain the real-time image information of the target site. After the flight control frequency band is interfered by the drone jammer, the drone will continue to fly uncontrollably until it is damaged or flies away from the range covered by the jammed signal. After the most important frequency band of GPS navigation and positioning is interfered by the drone jammer, the drone cannot lock the precise position of the ground target. At the same time, because of the lack of GPS coordinate information, the drone itself cannot perform automatic return to home. The flight mission at the take-off point.
