What design concepts are used in portable drone signal jammers?

As drones have grown in popularity among many different user communities, their prices have fallen from civilian prices. Because drones are often used in large quantities by terrorists, criminals and fanatics, they pose a great threat to people's privacy and life safety. Drone signal jammer products developed by the government have also begun to be widely used.

What is the principle of drone jamming technology?

There are two main types of jamming technologies, namely noise technology and repeater technology. Point jamming, sweep jamming, and barrage jamming are the three most common types of noise jamming, while DRFM jamming is the most common type of repeater jamming.

Point jamming: is a form of noise jamming where the jammer concentrates all its power on one frequency, making the technique ineffective for frequency agile radars.

Sweep jamming: is the process of transferring the full power of the jammer from one frequency to another. This "sweeping" motion interferes with multiple frequencies in rapid succession, although not simultaneously.

Barrage jamming: A single jammer jams multiple frequencies at the same time. The main disadvantage of this technique is that the jammer spreads its power over multiple frequencies, making it relatively weak on a single frequency.

Digital Frequency Radio Memory, or DRFM, is a repeater technology that confuses radar by altering and retransmitting received radar energy. For example, by changing the delay in pulse transmission, a jammer can change the radar's detection range and create false targets. Many jamming antennas use these types of techniques.

At present, there are various countermeasures against interference. Similar to jamming techniques, these countermeasures allow for varying degrees of effectiveness. In addition, specially designed anti-jamming antennas can be used. The development of electronic warfare continues to evolve as new RF technologies emerge.

In practice, everyone has also reached a consensus that for popular brands of drones on the market, portable drone jammers are roughly divided into jammer gun shapes and jammer shield shapes. Depending on the power, their interference distance is 100-2000M. In some special places, the effect of prohibiting drones from flying is very significant.
