DFJ Series
The DFJ Series is a stationary detection and defense system. Integrated detection and countermeasure capabilities, including detection, identification, positioning, and multiple jamming methods. The device features a professional-grade waterproof and dustproof
design, ensuring stable and reliable continuous operation in harsh outdoor environments.
Precise Identification
Detect and identify S/N ID, orientation, distance, latitude and longitude, flight altitude,and speed of the drone.
Precision Direction Finding
A single station can accurately determine the intrusion bearing of a drone and efficiently indicate the target bearing.
Networked Positioning
A single unit achieves precise direction finding, while all product series support AOA+TDOA fusion networked positioning, enabling regional collaborative defense.
Selectable Detection Distance
The device is available in multiple detection distance versions, allowing customers to select and configure the system based on the required distance of their defense perimeter.
Black and White List
One-click to mark the black and white list, keep the white-listed drones free from interference.
Defense and Jamming
Combined narrowband low-power precision jamming and wideband high-power interference.
