UAV jamming


At present, UAV jamming equipment on the market has a variety of categories and styles, including handheld gun type UAV jamming products, fixed installation on the roof of buildings, installation on street lamp poles, and vehicle mounted on the roof. This variety of UAV jamming equipment usually adopts two kinds of antennas: directional antenna and omnidirectional antenna. So the question comes: is it better to use directional antenna or omni-directional antenna when UAV interferes?

Directional antenna, as the name suggests, is that the interference signal is transmitted and transmitted in a main direction. The omnidirectional antenna is in the form of average diffusion around. Because the directional antenna has certain concentration characteristics, it shows that the performance of the directional antenna must be better than that of the omni-directional antenna in the direction pointed by the directional antenna.

But in the practical application of UAV jamming, is the directional antenna necessarily good? It's not. If only from the final effect of UAV interference, the interference distance of directional antenna must be greater than that of omni-directional antenna. However, UAV interference equipment, especially handheld gun UAV interference equipment, generally use directional antenna. Since directional antenna is used, it is equivalent to having determined the attack direction of UAV. Otherwise, Gun type UAV jamming equipment does not know which direction to point to for UAV strike. This brings another question: how to judge the attack direction of UAV? By human eyes? It is difficult to do this. If it only depends on human visual recognition, usually small civilian UAVs like Dajiang can be found only when the UAV is within two or three hundred meters from the observer. If the UAV really gets so close, it's too late to start the UAV jammer.

When can the UAV jammer use directional antenna to give full play to its best performance? The answer is yes, that is, if the UAV detection equipment is equipped, that is, the incoming direction of the UAV can be found and identified at a long distance. Then start the UAV jamming equipment, then the directional antenna can have a clear target and direction, and can concentrate the transmission power of the jamming signal to effectively attack the UAV.
