Product Description

TDOA Passive Geolocation System

The TDOA Passive Geolocation System is a passive geolocation device for low-altitude targets based on Time Difference of Arrival (TDOA) technology. Utilizing a multi-node acoustic/RF sensor array, the system captures signals emitted or acoustic waves generated by low-altitude targets—primarily UAVs—and calculates target coordinates with high precision by measuring the time differences in signal arrival across different sensor nodes. This enables passive detection, geolocation, and trajectory tracking of "low, slow, and small" (LSS) targets. The system requires no active signal transmission, offering core advantages including strong stealth capability, zero electromagnetic interference (EMI), and high positioning accuracy. It can be deployed independently or seamlessly integrated into broader low-altitude defense architectures, providing precise target location cuing for countermeasure systems. Widely deployed in sensitive facilities, airport clearance zones, border outposts, major event venues, and other critical areas, the system fills the passive geolocation gap in low-altitude defense and completes the low-altitude security situational awareness framework.

Core Product Features

Passive Geolocation with Exceptional Stealth

Employs TDOA passive geolocation architecture
Passively receives target signals only (UAV remote control signals, rotor acoustic signatures, etc.)
Transmits no active RF or detection signals of any kind
Zero electromagnetic radiation; inherently difficult to detect
Ideally suited for covert security operations in sensitive and classified zones

High-Precision Localization with Controlled Error Margins

Leverages multi-node sensor arrays combined with high-precision time synchronization technology
High geolocation accuracy with planar positioning error ≤5 meters
Precisely locks onto target coordinates and flight trajectories
Provides accurate data support for follow-on countermeasure deployment
Eliminates guesswork and avoids indiscriminate defense responses

Simultaneous Multi-Target Geolocation with High Efficiency

Simultaneously captures and geolocates multiple low-altitude targets
Rapidly performs multi-target coordinate calculation, trajectory tracking, and classification
