Counter-Drone RF Tools
Engineering calculators and reference databases for C-UAS professionals. All calculators run client-side — no data is sent to any server.
Drone Signal Database
DatabaseRF signal parameters for 92+ drone models — control frequency, video protocol, GNSS bands, and relevant RF planning bands.
Jammer Effectiveness Calculator
CalculatorUnified J/S ratio and authorized mitigation planning analysis. Enter scenario geometry to estimate received signal balance, effective range, and FHSS bandwidth penalty.
RF Detection Coverage Planner
PlannerEstimate passive RF sensor coverage from drone signal presets, receiver sensitivity, site geometry, radio horizon, environment loss, and multi-sensor overlap.
RF Detection Range Calculator
CalculatorCalculate the maximum distance at which a passive RF sensor can detect a drone's transmitter, given receiver sensitivity, antenna gain, and drone EIRP.
Free Space Path Loss Calculator
CalculatorCompute RF signal attenuation over distance in free space. Foundational for link budget analysis, jammer sizing, and RF sensor planning.
Methodology note: All RF calculations use free-space propagation models (Friis transmission equation). Real-world results vary with terrain, multipath, atmospheric conditions, and antenna polarization. Use these results as first-order estimates for planning — not as operational guarantees.
