UAV Detection
and
Electronic Countermeasure System
Overview
In order to meet customer requirements for countering UAV threats, NORTHBRIDGES provides a kind of UAV Detection and Electronic Countermeasure System to satisfied various customized requirements.
In addition to basic functions which include UAV model identification and UAV Direction-Finding, optional electronic countermeasure capabilities of the system also include GNSS spoofing, directional communication link jamming, omnidirectional communication link jamming, and narrowband jamming.
System transmits data and implements control on base of universal network protocols, supports custom software development if customer required.
The system is compatible with linking in user's integrated control platform and supports network connections and control functions from heterogeneous systems.
Features
UAV Detection and Electronic Countermeasure System is able to detect UAV signals which frequency range from 70MHz to 6GHz (Factory default ISM band is 2.4GHz and 5.8GHz).
Based on AoA Position technology (AoA) and Cognitive Radio technology (CR), Anti-UAV System is able to identify UAV model and track the UAV trajectory immediately after UAV being detected.
Based on amplitude-only direction finding (DF) technology, Anti-UAV system is capable of emitting dual-mode GNSS spoofing signals (GPS-L1, GLONASS-L1) accurately, providing virtual electronic fences for protected targets to prevent UAV intrusion effectively.
The system supports both manual operation and all-day automate operation. Under automate operation mode, it is able to accomplish the UAV identification, direction-finding, and GNSS spoofing (optional function) automatically, then trigger alert to command and control terminal immediately.
The system is capable of displaying, uploading and saving various information about the target UAV's flight trajectory in real time through a geographic information system.
Under manual operation mode, the system is able to provide operator with decision-making support information such as time of detection, UAV model,AoA via Command and Control Terminal. The operator decide to launch or not electronic countermeasures, such as Directional Communication Link Jamming (optional) , Omnidirectional Communication Link Jamming (optional) , or Narrowband interference (optional).
Under automate operation mode, the system is able to emit GNSS spoofing signal (optional) automatically, , then force UAV losing way, circling or mandatory landing.
