To shield the signal, the interferer transmits radio frequency power (CW+ modulation) at the opposite frequency to the enemy link or network. The friend’s receiver (the “listening” part) will receive both the drone signal jammer transmission and the “companion” transmission. If the drone interferes with the “companion”‘s power supply, the “receiver” will not be able to properly “understand” the audio/data. Perhaps, if the strength of the “companion” is greater than that of the disturber, the “listener” may be able to “understand” the audio/data correctly, and the communication link between the “companions” will remain uninterrupted.
This happens because the receiver usually needs some “headroom” between the two signals at its output so that one (usually the loudest) can be interpreted. However, in advanced communication systems, this “margin” can sometimes even be a positive number (meaning that the communication signal can be much weaker than the jamming signal), and the receiver can still interpret the “companion” signal and thus alter the jamming. This is more difficult.
Usually in anti-drone use, the purpose is to thwart the drone at a distance of several hundred meters from the sensitive area/equipment (the center of the device’s signal protection cover). For example, we want a drone that is 300 meters away from signal blocker and 10 meters high. It can be understood that in this condition, the diagonal separation between the signal shield and the drone is approximately the same as the horizontal separation between them. So, for the sake of complexity, we’ll talk about degree intervals, which we don’t mind when calculating the exact interval, since the difference is quite small.
(no cable loss, SNR, etc.), it can be used to calculate any disturbance scenario/budget. As you can see, it consists of two dimensions/links (jammers <-> drones and operators <-> drones), not just one dimension/link, like the communication link. In other words, for each specific condition of carrier link <-> drone (specific output power, antenna gain and height, spacing, etc.), jamming link <-> drone has specific conditions/conditions To stop it…that’s why you answer “What’s the range of your drone jammer?” This achievement is not an easy task.
