RF receive paths for drone detection
Drone detection uses RF receive hardware to observe signals associated with small unmanned aircraft, remote controls, telemetry channels or video links. The emphasis is on finding and monitoring signals before any mitigation or response chain is considered.
Detection boundary
A receive path may include directional or sector antennas, low-noise amplification, filtering, frequency conversion, detection paths and spectrum monitoring. Sensitivity, dynamic range, antenna placement, bandwidth, local interference and scan strategy shape the detection result.
Useful data
Useful records include monitored bands, antenna pattern, receiver noise figure target, filter bandwidth, conversion plan, detector threshold, scan dwell time, site interference, cable loss and environmental exposure.
Treat spectrum monitoring as an evidence chain

- Drone Detection RF testing and verification
- Verify the installed chain and preserve enough evidence to repeat the result Use a conducted path to characterize gain, noise, filters, image and spurious responses, IP3 or overload and amplitude accuracy; then repeat representative checks through the installed antenna path with known site signals or a controlled field source....
Spectrum Monitoring Receiver Front Ends: Dynamic Range, Scan Coverage and Verification
Specify a spectrum-monitoring receiver from antenna coverage to recorded evidence by balancing weak-signal sensitivity, strong-signal tolerance, preselection, instantaneous bandwidth, RBW, dwell, revisit time, thresholds, timing and calibration.
