01
Temporal / Duty-Cycle Manipulation
Pulsed Jamming
Cyclic on/off defeats AGC and conserves transmitter power
→
Stochastic Pulsing
Random intervals make filtering or prediction nearly impossible
→
Burst-Synchronized Jamming
Fires only on detected uplink bursts — minimal emissions signature
→
02
Protocol / Behavioral Exploitation
Deauth Injection
802.11 deauth flood disconnects without wideband noise
→
ACK Starvation
Jam only ACK slots in TDMA/FHSS — forces retransmit loops
→
Hop Prediction Jamming
Predict next FHSS channel via clock analysis — jam one step ahead
→
03
Directed / Spatial Techniques
Null-Steering Jamming
Phased array beams on target while nulling toward friendlies
→
Follow-Me Tracking
Beam steered continuously to moving target via AoA / Doppler
→
Link-Selective Jamming
Jam uplink only — C2 denied while video downlink stays up for intel
→
04
Signal Design Techniques
Swept / Chirp Jamming
Continuous freq sweep covers all FHSS hops over time
→
Spot + Barrage Combination
High-power spot on control link, wideband on GPS simultaneously
→
05
Effect-Shaping — Induced Behavior
RTH Induction
Jam control link only — drone autonomously returns to home point
→
Hover-Lock
Jam control link on hover-hold platforms — drone freezes for ID
→
Geofence Spoofing
GPS spoof moves drone's perceived location into a no-fly zone
→
06
Covert / Low-Probability-of-Intercept
Noise-Floor Creep
Raise noise floor just below detection threshold — link degrades silently
→
Fractional Bandwidth Jamming
Target only pilot/sync subcarriers in OFDM — receiver loses sync quietly
→
Editorial note: Two techniques — coherent/matched jamming and parasitic injection — are omitted from this taxonomy. Both sit at intersections (signal collection + spreading-code analysis; EW + cyber) that require extended treatment to avoid misinterpretation. Long-form write-ups forthcoming.
Defender's View
Countermeasures & Platform Hardening
Understanding the attack surface is the foundation of resilient platform design. Each technique above has a corresponding hardening response — and understanding both sides is what makes effective C-UAS doctrine possible.

Redundant GNSS + IMU
Multi-constellation + inertial fallback defeats spoof and jam

Fiber-Optic Tether
Eliminates RF attack surface entirely for tethered platforms
