Anti Drone 20km Laser Rangefinder Module

A 20 km laser rangefinder module is a powerful component in modern anti-drone systems, offering precise, long range targeting capabilities. When integrated with other sensors and countermeasures, it forms a robust defense layer against unauthorized drones.

Key Features of a 20km Anti Drone Laser Rangefinder Module

1. Range: Up to 20000m, and more than 25000m for big builds, drone rangefinder module can vary based on target size, atmospheric conditions, and laser power.

2. Laser Type: Typically pulsed 1535nm eye-safe laser.

3. Accuracy: ±1–3 meters at 20km rangefinder module.

4. Repetition Rate: High speed pulse repetition rate 1–5Hz for real-time tracking.

5. Target Size: Capable of detecting small UAVs.

6. Beam Divergence: Low divergence and OEM mrad for long range precision.

7. Integration: Designed for integration into anti-drone systems, radar, or command centers.

8. Environmental Resilience: Operates in day/night, fog, dust, and low-light conditions with RS422 signal processing.

How It Works in Anti-Drone Systems

1. Detection: The 20000m laser rangefinder module emits short, high-energy pulses toward the sky.

2. Reflection: A drone reflects part of the laser beam back to the receiver.

3. Time-of-Flight Measurement: The anti drone rangefinder module calculates distance using the time it takes for the pulse to return.

4. Tracking: Combined with gimbal-mounted optics and AI-based tracking software, the 20km laser rangefinder module can follow moving drones.

5. Handoff to Countermeasures: Once locked, data is sent to jammers, net guns, or kinetic interceptors.

Advantages Over Radar-Based Systems

Higher accuracy and resolution.

Less susceptible to clutter,no false echoes from birds or terrain.

Can operate in RF jamming environments, non-electromagnetic.

Excellent for identifying small, slow-moving drones.

Typical Applications

Military perimeter defense

Airports and critical infrastructure protection

Government facilities and embassies

Large-scale events such as Olympics and concerts

Border security
