Anti drone system UAV disruptor portable

We all know that we can use anti drone disruptor system to interfere with equipment flying below drones. What is the working principle of drone signal blockers? In the offensive and defensive situation, there is usually a distance between the operator of the drone and the sensitive area that needs to be fortified. The drone takes off from the vicinity of the operator and then gradually flies to the fortification area. When the drone reaches the vicinity of the fortification zone and is capable of conducting effective detection or sabotage activities, the distance from the drone to the fortified zone is usually much closer than it is to the operator.

In this case, all the uplink signals sent by the operator (sent from the ground to the drone) will be weak because of the distance. With the same power, the drone jammers is closer to the drone and the signal will be stronger than the operator. The disrupt signal received by the signal jamming device will also be stronger than the operator. However, the defense target for the downlink signal is that the operator does not receive it, and the distance from the drone to the operator is similar to the distance from the defender to the operator. Therefore, blocking the downlink signal does not occupy the terrain advantage.

At this time, it is more advantageous to interfere with the uplink signal. It happens that the uplink signal is usually a remote control signal, which is directly related to the control of the drone. If the uplink signal is disturbed, the drone will lose its immediate control and can only operate according to the preset steps of the program (usually landing or hovering). The downlink signals are mainly telemetry and images. Although there may be sensitive information, it is less important than the control signal. In addition, the defender does not have an advantage in the situation, and usually adopts a laissez-faire attitude to the downlink signal.
