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.
