SX-F302 Enhanced Detection & Countermeasure Drone Defense System

System Component Introduction

The SX-F302 enhanced system consists of one SX-F302 detection & countermeasure unit (for low-altitude drone detection and suppression) and a back-end management & control platform (for real-time monitoring and regulation of low-altitude flights). Powered by an adapter converting AC220V to DC24V, it allows flexible deployment for all scenarios.

The SX-F302 unit supports fixed installation. It conducts front-end data processing on-site and uploads data via 4G modules or LAN networking. Uploaded data is analyzed by the control platform, which sends commands to front-end units to suppress low-altitude drones. Front-end data can also be processed and uploaded via dedicated 4G workstations to the cloud platform for mobile terminal remote control.

1. SX-F302 Enhanced Unit

The SX-F302 unit integrates drone detection and countermeasure functions. It detects illegal intruding drones through radio frequency scanning, feature recognition and signal decoding, capturing control and video transmission signals between drones and remote controllers. It supports 7×24-hour uninterrupted monitoring and recording to build an all-weather no-fly zone as an effective defense barrier. Via electromagnetic suppression technology, it fully jams drone control links, video links and navigation signals to force return or emergency landing. It supports standalone and networked operation with high integration and flexible all-in-one design.

2. Management & Control Platform

As the core service hub, the platform accepts data input from all detection sensors and connects fixed and portable units via multiple network channels. It aggregates, analyzes, stores and processes detection data, displays real-time detection information and online status of all connected devices, and supports remote operation. Preset response strategies, alarms and log functions are built-in. Interconnection between multiple platforms enables cross-node information sharing.

Figure 2 Management & Control Platform Interface

The SX-F302 system applies to railway line protection, office parks, industrial facilities, large-scale events, rapid deployment, VIP escort, SWAT anti-riot operations, concerts, conferences, airports, examination venues, prisons, military sites, courts, meeting rooms, cinemas, hospitals, government agencies, financial institutions, religious venues, libraries, business negotiations, gas stations and privacy protection – all locations requiring quietness, confidentiality and information security. It is especially suitable for wide-range supervision in special scenarios.

A single SX-F302 unit independently completes drone detection, positioning and jamming to deliver full low-altitude protection anywhere. Deployed in open unobstructed terrain, one station achieves detection and positioning within a 12,000-meter radius to easily secure the above scenarios.

· Detection radius: 0–5,000 m (subject to local electromagnetic environment)

· Jamming radius: 0–2,000 m (subject to local electromagnetic environment)

1. Detection & Early Warning

drone intrusion early warning function: front-end detectors compare real-time signal data with the back-end drone spectrum feature library, supporting unattended all-time all-weather operation with automatic risk grading. Simultaneously detects multiple intruding drones and triggers multi-dimensional alarms via voice and indicator lights immediately upon illegal intrusion.

2. Precise Jamming & Suppression

The system adopts soft-kill countermeasure technology. It suppresses drone control and video signals via 360° omnidirectional or directional jamming to deprive drones of remote control and navigation, forcing return or forced landing. The platform automatically selects optimal suppression strategies based on threat level and environmental factors, and feeds back suppression results and geographic data to the control interface for display.

3. All-Weather Detection

Powered by advanced radio scanning and feature recognition, the system efficiently detects illegal drones within a maximum 12 km radius. It accurately captures and decodes control and video signals between drones and operators for zero omission. Continuous 7×24-hour monitoring and recording build an all-weather blind-spot-free no-fly zone as a robust defense solution. It detects mainstream consumer drones including DJI, Autel, Fimi, Dahua, Hubsan, plus self-built racing drones and WiFi drones with agile detection capability.

4. Networking Function

The SX-F302 system connects to the management platform via LAN, 4G/5G modules and other network links to upload detection data and countermeasure status.
