Radar Banned in Sensitive Areas? Passive Drone Detector for Zero-EMI Urban Airspace Security

Deploying drone defense in cities comes down to one contradiction: you need wide-area coverage, but you can't add electromagnetic pollution. Traditional radar actively emits signals, making it unsuitable around airports, government buildings and hospitals. Single-station DF only gives a rough bearing — no exact coordinates, no pilot location.

The TQ01 solves this with passive detection + TDOA networked positioning. A single unit emits zero signals while receiving in 360°; grid-deployed units fuse to output precise coordinates of both drone and pilot. Zero EMI makes it ideal for urban and sensitive-zone deployment.

100MHz–6GHz Full-Band Passive Detection, Spotting Targets 10km Away

Single-Station DF + Multi-Station TDOA, 20m Accuracy Locks the Pilot

The TQ01 uses a passive spectrum reception architecture covering the full 100MHz to 6GHz band (Evidence: Product Technical Specification), with 360° omnidirectional reception. It recognizes over 500 drone models from mainstream brands including DJI, Autel, FIMI, Dahua and Yuneec, as well as custom-built racing drones and Wi-Fi UAVs. In open environments, detection range reaches 1 to 10km, simultaneously tracking ≥30 targets.

A single unit performs direction finding across 2GHz to 6GHz with ≥3km DF range and approximately 10° accuracy (Evidence: Product Technical Specification), displaying real-time drone bearing on an electronic map. When multiple TQ01 units are networked, TDOA fusion delivers ≤20m positioning accuracy and ≥5 simultaneous target tracks — not only locking the drone position but also locating the pilot's remote controller, providing precise coordinates for law-enforcement action.

Spectrum Scanning + Anomaly Detection, Smart Recognition of 500+ Models

The device supports full 100MHz to 6GHz spectrum scanning with real-time spectrogram and waterfall display (Evidence: Product Technical Specification). The system automatically identifies anomalous signals and flags them in a list, helping security personnel distinguish legitimate transmissions from intrusion signals. It triggers audible and visual alarms on drone intrusion, retains complete detection records, and supports flight trajectory playback and historical data analysis.

Standard API interfaces allow detection data to be uploaded to third-party management systems; electronic maps support Amap, Baidu and offline Google switching to suit different regional usage habits.

Integrated 8-Channel Jammer Box, Detection-to-Countermeasure Linkage

The TQ01 links with a fixed jammer box to close the "detect-locate-neutralize" loop. The jammer box features 8 RF channels covering 430MHz to 5.86GHz (Evidence: Product Technical Specification), with 100W output on the three main bands — 2.4GHz, 5.2GHz and 5.8GHz. Jamming range is 1 to 3km with ≤30s response time. Antenna swap enables switching between omnidirectional and directional modes; built-in intelligent cooling delivers MTBF ≥1000 hours for long-term outdoor deployment.

As urban airspace control requirements rise, restrictions on active-emission radar in sensitive zones are tightening. Passive detection + TDOA networked positioning — zero EMI, high accuracy, grid scalable — is becoming the mainstream route for airports, government compounds and large campuses.When selecting, prioritize three dimensions: single-station DF and multi-station TDOA precision for law enforcement, true passivity for EMI-sensitive zones, and mesh scalability with open APIs for platform integration. The TQ01 delivers on all three — an ideal front-end node for city-scale airspace sensing networks.
