Spread Spectrum Techniques for Anti-Drone Evasion
Explores implementing low-cost frequency-hopping spread spectrum algorithms on DIY and consumer drones to resist RF jamming and anti-drone interception.
Summary
RF Warfare Against Consumer and DIY Drones
Commercial and hobbyist unmanned aerial vehicles (UAVs) increasingly face electronic warfare countermeasures, where targeted RF jamming disrupts control links and GPS navigation.
Frequency-Hopping Spread Spectrum on Budget Hardware
David Melendez and Gabriela Garcia demonstrate how to implement frequency-hopping spread spectrum (FHSS) on low-cost microcontrollers without requiring expensive precision clocks.
Solving Transmitter-Receiver Synchronization
Developing lightweight software synchronization algorithms allows drone transceivers to rapidly hop frequencies in tandem, maintaining reliable control links amidst electronic interference.
Defeating Anti-Drone Detection and Disruption
Experimental testing demonstrates that agile frequency hopping severely degrades the effectiveness of directional RF jammers and unauthorized drone interception systems.
