Case Study

Passive RF and acoustic cues for a defense prototype workflow.

PASSIVE-SHIELD demonstrates public-safe prototype evidence for passive DJI/OcuSync-family RF cues, acoustic corroboration, edge status, event sharing, and operator review.

Problem

Defense prototype cues need evidence, context, and careful boundaries.

A useful sensing prototype needs more than an alert. It needs station state, signal-family evidence, corroboration, duplicate suppression, operator context, and a public claim boundary that does not imply fielded operational C-UAS capability.

System Built

Passive DJI/OcuSync-family RF evidence workflow
Acoustic corroboration and edge-station event context
Operator map and cue review surfaces
Trace Analyzer timeline context beside BLE, GPS, WiFi, and other RF events

PASSIVE-SHIELD public-safe operator map — Public-safe operator map using a non-operational random location background and sanitized cue context.

Trace Analyzer timeline with PASSIVE-SHIELD prototype events — Trace Analyzer view showing PASSIVE-SHIELD prototype events beside BLE, GPS, WiFi, RF Sentinel, and SDR-Shark context.

Technical Approach

Represent cues as source-aware events rather than isolated alerts
Preserve passive RF signal-family evidence and station context
Use acoustic corroboration as supporting evidence in the prototype chain
Route public-safe event context into Trace Analyzer for timeline review

Proven and Not Claimed

Proven: passive RF, acoustic, station, and operator cue evidence can be connected in a prototype workflow
Proven: prototype cues can be reviewed in a broader source-aware timeline
Not claimed: fielded operational C-UAS capability, jamming, spoofing, or defeat
Not claimed: pilot location, home point, payload, serial, GPS decode, precision geolocation, or universal drone detection
