Reinforcement Learning Dynamic Frequency Hopping for Contested Datalinks
The Electronic Warfare Battlefield Crisis
In Ukraine and contested naval zones, Russian and peer EW systems sever drone command links and video feeds within minutes using barrage and swept jamming.
Static frequency-hopping spreads blindly across pre-programmed tables, inevitably landing on jammed channels and dropping 30%–50% of critical packets.
The Cognitive Q-Learning Solution
SpecGuard embeds a lightweight Q-learning agent directly into tactical Software-Defined Radios (SDRs).
By learning packet delivery acknowledgments (ACKs) and spectral noise in real time, it identifies and permanently avoids jammed channels within under 50 hops, sustaining >95% mission success.
A single hostile jam drives the channel utility into deep negative territory, forcing immediate cognitive frequency diversion.
Adaptive Epsilon Exploration Decay
Initial exploration rate (ε = 0.35) surveys the 10-channel spectrum during the first 10 hops.
Decays exponentially to ε = 0.02, locking into high-throughput clear frequencies while maintaining a 2% pulse to detect when previously jammed channels clear.
Overall Mission Success:92.0% total packets delivered.
Execution Latency:0.08 ms per hop decision (SDR COTS ready).
Sweeping Jammer Resilience
When an agile enemy jammer shifts from channels 3 & 7 to channels 2 & 8, SpecGuard detects the new NACKs, re-inflates local exploration, and re-converges to new clear bands in under 8 packet cycles.
Standalone IP Valuation:$5.5M – $8.0M ($4\times\text{–}6\times$ Year 1 ARR, benchmark for deployable tactical EW IP).
Strategic Buyer Advantage: SDR manufacturers or drone primes (AeroVironment, Skydio, Anduril) can patent the asymmetric ACK-penalty hopping algorithm and market unjammable radio links as an exclusive capability.
Seed Growth Financing
Seed Raise Ask: $2.0M on a post-money SAFE ($11M cap).
Milestones: FPGA/GNU Radio hardware bench verification, over-the-air EW range tests, and flight certification on Group 2 UAS.
