The use of drone jammer systems to defend against black flying or illegal intrusion of drones has become an important safeguard measure for many secret places, key military departments and key protected areas. The units that need to be protected, the drone countermeasure equipment purchased and installed comes from various manufacturers, and the models and specifications are not the same. Then the problem is coming. There are a large number and variety of drone interference. Is the effect of the drone system the same for all kinds of drones?

All defenses against drones mainly include: 1. drone detection and identification, 2. drone expulsion, drone forced landing (or drone strike). What we are discussing here is mainly the case of category 2.

The key point of the drone jammer system is to jam the drones that have been discovered, and this jamming effect can be to drive the drones away from their own area. It can also be forced to land or captured directly. When we talk about the effect of interference, we usually mean the effective working distance or working radius of the interference.

The specific analysis of the interference effect should be carried out from two aspects: the first is the performance index of the drone jammer system itself, which includes the wireless communication frequency bands commonly used by drones covered by its interference signal, and also includes various signals. The transmit power of the jamming module, and at the same time, the directional antenna or omnidirectional antenna it configures determines the quality of its jamming effect. The second point is to analyze from the perspective of drones, because the drone market is now prosperous, commercial drones for civilian use can be said to be inundated, and drones of different brands, models and functions emerge in an endless stream. The performance indicators between these drones are very different, not only the difference in communication frequency bands, but some drones have enhanced anti-jamming capabilities, and there are even some privately modified drones that enable some unconventional Communication module, and try to increase the power of the transmitter and receiver module of the remote control of the drone. This is a bit similar to the relationship between the spear and the shield. They are compared with each other. The biggest reason that affects the results of the test is to see who is launching The higher the power, the stronger the anti-interference ability.

Based on the above analysis, we can conclude that the effect of the drone jammer system on various drones will definitely not be exactly the same. The update iteration of drones is very fast, and the drone jammer system must also follow up gradually. This is bound to be a mutually progressive and mutually competitive process.
