AI High Sensitivity Air Defense Radar Border Surveillance Radar

AI-Enabled High-Sensitivity Border Surveillance Radar System with Full-Spectrum UAV Detection

I. Core Functions and Technical Principles

1. High-Sensitivity Radar Technology

   • Frequency Band: Ku/Ka bands (12-40 GHz), balancing detection accuracy (centimeter-level resolution) and anti-precipitation interference.

   • Sensitivity: ≤-120 dBm (typical), detects micro-UAVs (e.g., DJI Mavic series) with 0.01 m² RCS at 5 km.

   • Doppler Effect: Velocity filtering (0.3-50 m/s) to distinguish UAVs from birds (>15 m/s typically).

2. All-Weather Detection

   • Adaptive environmental compensation: Automatically increases transmit power (up to 500W) in sandstorms/snow.

   • Thermal imaging: Integrated uncooled IR detector (8-14 μm wavelength) with >92% nighttime recognition rate.

3. AI Recognition Engine

   • Machine learning: ResNet-50 model trained on 200,000 datasets of UAV/bird/helicopter features.

   • Real-time classification: Identifies mainstream UAV brands (DJI/Autel) within 0.2 seconds.

II. Full-Coverage Deployment Solutions

1. Fixed Radar Arrays

• Density: 3 radars per 50 km border (120° sector coverage), using TDMA to avoid interference.

• Networking:

  • LoRaWAN backhaul (15 km range, <5W power consumption)

  • Data fusion center with Kalman filtering algorithm

2. Mobile Detection Units

• Vehicle-mounted radar:

  • 12-m retractable mast for low-altitude coverage

  • Hydrogen fuel cell (72-hour endurance)

• Counter-UAV vehicles: Integrated dual-band (2.4/5.8 GHz) microwave jammer

3. Layered Defense System

III. Key Technical Parameter Comparison

IV. Application Scenarios

1. Illegal Border Crossing Detection

   • Forest penetration: Detects human movement (Doppler signature 0.5-2 m/s)

   • Integration with vibration-sensing fiber optic systems (±3m accuracy)

2. UAV Swarm Defense

   • Identifies swarm attacks (>10 UAVs), activates anti-saturation mode

   • Locates operators via RF triangulation (<100m error)

3. Emergency Response

   • Wildfire monitoring: Predicts fire spread direction

   • Search-and-rescue: Provides real-time terrain avoidance for helicopters

V. Cost & Deployment Recommendations

1. Initial Investment

   • ~$150,000/km (equipment + installation)

   • Reduces manual patrols by 60% vs. traditional CCTV

2. Maintenance

   • Predictive maintenance: Radar Health Index (RHI) gives 14-day fault预警

   • Modular design: TR module replacement in 20 minutes
