The Ukrainian military uses mobile radars for early detection of enemy FPV drones at a distance of several kilometers. Once the target is detected, interceptor drones are launched into the air.

The Ukrainian military unit "Birds of the Magyar" reported on a new method of intercepting Russian FPV drones using fiber-optic control. It involves the use of mobile radars for early warning of the approach of FPV drones at a distance of several kilometers. The War Zone observers told more about this.
A video of a Russian UAV intercepted on fiber optics was published in the publication of Robert Brovdy, with the call sign "Magyar". Commenting on the footage, analysts explained that after detecting an enemy FPV drone, interceptor drones take to the air, capable of destroying Russian aircraft before they reach their target.
A distinctive feature of Russian FPV drones is a massive coil at the stern containing a strong but thin cable that connects the drone to the operator. Thanks to this control, the drone maintains communication even when flying close to the ground and inside buildings, which makes it especially dangerous in combat conditions.
Interception of Russian FPV drones: how it happens
And although Brody did not disclose the exact characteristics of the radars used, it is likely that they are Ku-band microwave systems optimized for detecting small, slow-moving targets.
However, experts say such devices have a limited range, making them effective only within a few kilometers. But if such radars are placed on mobile platforms closer to the front line, they can detect threats in a timely manner and coordinate the actions of interceptor drones. Brody emphasizes that the mass deployment of such systems is critical for protecting the front line.
The commander of "Birds of the Magyar" emphasized that Ukraine urgently needs to deploy mobile radars along the entire front with intervals of 2-4 km in order to effectively intercept enemy FPV drones. Moreover, such systems will be useful not only on the battlefield, but also in peaceful regions: they can be installed on military bases and strategic facilities.
At the same time, their radiation can be detected by the enemy and used for targeting. Therefore, placing radars on mobile platforms increases their survivability, but does not completely solve the problem.
“However, their necessity indicates that in the near future, advanced sensors for combating drones will be absolutely necessary wherever troops are present, and especially on an active battlefield,” the experts concluded.
