Most Drones Don't Want to Be Detected

Three detection approaches for different consumer-grade drone types:

RID Detection
WiFi and Bluetooth capture Remote ID broadcasts. Shows compliant operators in your airspace. https://github.com/Root-Down-Digital/DragonSync-iOS

Encrypted FPV
DJI OcuSync, HDZero, Walksnail. SDRs detect encrypted signals without decoding. SDRs confirm presence without payload access. https://github.com/alphafox02/antsdr_dji_droneid

Analog FPV
Unencrypted 5.8GHz video. SDRs pick up older FPV systems broadcasting in the clear. https://github.com/lscardoso/gr-ntsc-rc

FPV drones don't always broadcast Remote ID. They're fast, maneuverable, and built to stay off the grid. Detection requires monitoring all three.
