As Ukraine introduces high speed drone interceptors to defeat Russian “Shahed-136” (Rus: Geran-2) kamikaze UAVs, it should be anticipated that the Russians will react with countermeasures.
The battle between Russian reconnaissance UAVs and Ukrainian FPVs provides a template.
1/
Special Ukrainian FPVs began intercepting and destroying large numbers of reconnaissance drones such as “Zala” and “Supercam”.
The Russians first responded with an EW system that detected the video signal of the FPV, and initiated strong jamming in that frequency.
2/
This system apparently had some success, but was replaced by a rear-facing camera and an automated evasion program, possibly with some machine learning.
Upon sighting an approaching FPV, the Russian UAV automatically turns and dives, significantly complicating final attacks.
3/
The rear cameras with evasion would most likely be the first countermeasure mounted on Shaheds if the Ukrainian interceptors continue their successes.
The recently seen Shahed with AI autonomy and terrain following is likely much too expensive to be made in large numbers.
4/
Shaheds use satellite navigation, and the struggle between increased Ukrainian EW jamming and more jam-resistant Russian CRPA antenna systems will continue.
The first 4-element “Cometa” has been replaced with 8, 12, and now 16 element CRPAs produced by Russia, China, and Iran.
5/
Controlled Reception Pattern Antennas resist jamming by adjusting reception.
Using multiple elements directions of minimal sensitivity are steered towards a jammer, while maintaining gain for GPS signals.
Adaptive beamforming counters multiple jammers, giving stable reception.
