LiDAR & RADAR

🔷 LiDAR (Light Detection and Ranging)

What it is:
A sensing technology that uses laser light pulses to measure distances and create high-resolution 3D maps of the environment.

How it works:

  • Emits laser beams
  • Measures the time taken for light to bounce back
  • Calculates distance and shapes in 3D

Key Features:

  • High precision and resolution
  • Effective for detailed mapping
  • Works best in clear weather

Use Cases:

  • Autonomous vehicles (detecting road objects)
  • Robotics (navigation)
  • Drones (terrain mapping)
  • Smart cities (traffic monitoring)

🔷 RADAR (Radio Detection and Ranging)

What it is:
A system that uses radio waves to detect objects, measure their distance, speed, and direction.

How it works:

  • Emits radio signals
  • Receives reflected waves from objects
  • Calculates distance and motion (Doppler effect)

Key Features:

  • Works well in low visibility (fog, rain, night)
  • Lower resolution than LiDAR
  • Better for tracking moving objects

Use Cases:

Military and security surveillance
ADAS systems (detecting vehicles in all weather)
Aviation (altitude and aircraft tracking)
Maritime navigation
