🔶 Key Features

1. Frequency-Tracking Smart Jamming

• Uses full-band fast-frequency hopping and multi-range antenna technology.

• When within line-of-sight of the drone controller, the system intercepts and degrades uplink control signals.

• Emits agile omni-directional jamming to disrupt frequency-hopping UAVs.

• Concentrated energy output ensures a superior Jam-to-Signal (J/S) ratio compared to traditional broadband suppression.

• Supports ultra-wideband modulated jamming (up to 400 MHz per channel) for GNSS or non-standard UAV control links.

2. Comprehensive Data Logging & Traceability

• Automatically records:

  • Detection activity

  • Device status

  • User operations

• Supports maintenance, jamming performance evaluation, and operational accountability across the full lifecycle.

---

3. Intelligent Tracking & Spectrum Visualization

• Continuously tracks and holds frequency-hopping UAV signals under guided conditions.

• Enables coordinated UAV reconnaissance + jamming while maintaining target lock.

• Provides real-time 2D spectrum analysis and 3D waterfall displays for rapid signal identification.

---

4. Omni-Domain Multi-Mode Jamming

• SDR-based platform covering 0.4‒6 GHz.

• Omni-directional, dual-polarized transmission.

• Supports multiple jamming waveforms:

  • White noise

  • High-speed sweep

  • BPSK

  • Agile interference

• Effectively cuts UAV control links across the entire protected area.

---

5. Adaptive Anti-Interference Stability

• Equipped with high-performance RF pre-selection components.

• Ensures stable operation in dense urban electromagnetic environments.

• Minimizes external interference impact on both detection and jamming performance.
