Product Description

Product Description

JDY-400 Fixed-Type UAV Omnidirectional Countermeasure System

Product Overview:
JDY-400 Fixed-Type UAV Omnidirectional Countermeasure System

The JDY-400 System adopts a highly integrated UAV omnidirectional countermeasure design, and is suitable for the petrochemical industry, power systems, industrial facilities, vehicle-mounted applications, and rapid deployment. Through 360° omnidirectional electromagnetic interference, it suppresses UAVs' remote control signals, image transmission signals, and navigation signals. A single device can implement radio interference countermeasures against UAVs, causing UAVs to return to their takeoff point or make an emergency landing after losing signal connectivity. This protects airspace from unauthorized UAV intrusions and provides comprehensive low-altitude protection anytime and anywhere.

The system supports wireless communication and enables flexible network expansion; multiple stations can achieve wireless grid-based intelligent management and control. Its features include full radio frequency band coverage for UAVs, and it meets the requirements of 24/7 all-weather operation.

Application Scenarios:

JDY-400 Equipment are widely used in multiple fields to address UAV threats:The JDY-400 System boasts a wide range of application scenarios across multiple fields, encompassing UAV (Unmanned Aerial Vehicle) patrol and countermeasures in low-altitude areas. These areas include VIP escort missions, special anti-riot operations, concerts, large-scale conferences and events, airport management, examination halls, prisons,  installations, courts, meeting rooms, cinemas and theaters, hospitals, government agencies, financial institutions, churches, temples, libraries, business negotiations, gas stations, personal privacy protection sites, and other venues where quietness, confidentiality, and information security are required.

The system can work in coordination with radio detection equipment. This equipment provides intrusion information of target UAVs, such as intrusion direction, distance, and angle. The JDY-400 System then delivers precise strikes against target UAVs through omnidirectional radio jamming and countermeasures.

Additionally, the JDY-400 System is applicable to hazardous chemical parks (including those for petrochemicals and natural gas) as well as units with power usage restrictions. It can also be used in sports events, other types of activities, and industrial parks. Furthermore, it serves the security needs of key areas like vital points, airports, and petrochemical facilities. The system enables effective and timely UAV countermeasure disposal against unauthorized UAVs in low-altitude airspace, ensuring that parks, border defense zones, sports events, major activities, key areas, and important venues remain free from interference and threats.

Main Functions:
JDY-400 Equipment
Precise Jamming & Countermeasure
Adopts soft-kill technology with customizable frequency modules (GPS/Beidou, 2.4GHz, 5.8GHz, etc.). Achieves 360° omnidirectional electromagnetic interference to block UAVs' remote control, image transmission and navigation signals, forcing UAVs to return or land. The control platform automatically selects optimal countermeasures based on detection data and external factors; covers mainstream consumer UAVs (DJI series, Autel, etc.).

Networking & Grouping
Supports 4G/5G and LAN access for multi-device integrated networking and centralized management. Reserves data sharing interfaces to connect with external systems, meeting grid-based intelligent management needs.

Visual Monitoring & Air Situation Management
Tracks intruding UAV coordinates to form accurate trajectories; links with photoelectric tracking turntables for automatic target tracking and image acquisition (UAVs & payloads). Analyzes detection/identification/disposal info to form comprehensive air situations, formulates response plans, and sends intrusion notifications to relevant terminals.

Detection & Early Warning + Precise Positioning (Requires Radio Detection Equipment)
Compares detection signals with UAV spectrum databases to identify UAV type, brand, model and unique ID. Locates UAV (longitude/latitude, direction, distance) and pilot (remote controller position). Supports multi-UAV detection and real-time early warning via voice and warning lights.
