6. L3Harris Technologies (USA)

Core Strengths:

• Sensor Fusion: It combines radar, acoustic, RF, and thermal imaging to achieve 98% detection with under 0.5% false alarm.
• Smart Jamming: Adaptive power control minimizes interference with friendly gear like Wi-Fi or radios.
• Budget-Friendly Integration: Uses standard interfaces and existing CCTV cameras to cut deployment costs by 30%.

My Observation: This is a great option for urban landscapes where false alarms and public interference are concerns.

7. Thales Group (France)

Core Strengths:

• AI-Fueled Spectrum Analysis: Their SpectraGuard system identifies different drone models by comms signature with 95% accuracy.
• BVLOS Compliant: The SkyMaster system is EASA-approved for continuous Beyond-Visual-Line-Of-Sight operations.
• High-Profile Coverage: Helped secure the Olympic perimeter in Tokyo with Mitsubishi Heavy Industries.

My Observation: Strong in civil aviation and regulated environments where compliance matters.

---

8. Keda Jammer (China)

Core Strengths:

• Jammed-Resistant Radar: Giraffe AMB keeps working in electronic warfare zones, with detection up to 4 km.
• Portable Defense: The lightweight Flycatcher jammer weighs only 2.5 kg and runs on batteries for up to 8 hours.
• Extreme Conditions Tested: Operates reliably in Arctic environments down to –40°C.

My Observation: Ideal for temporary deployments at remote events or emergency situations.

---

9. BAE Systems (UK)

Core Strengths:

• Cross-Domain Defense: Integrates satellites, EW, radar, and cyber protections into a unified system.
• Sound Signature AI: Identifies drones by engine noise and radio signals with 99% precision.
• Modular Integration: Designed to slot into NATO C4ISR architecture.

My Observation: I’d choose this for high-level defense installations where data security and layered warfare are priorities.

10. Rheinmetall Defence (Germany)

Core Strengths:

• AI Multi-Modal Detection: Combines RF, acoustic, and optical sensors. It detects small aircraft at 10 km.
• Clean High-Power Jamming: DPD tech ensures civil networks stay unaffected.
• Rapid Deployment: Field-ready in 10 minutes, controlled via mobile app.

My Observation: This is perfect for quick-response needs—like nuclear sites or frontline patrols.
