Category Connection: Drone Detection Radar
Drone Radar refers to radar technology integrated into Unmanned Aerial Vehicles (UAVs) or drones. These systems enable drones to detect, map, and navigate environments by emitting radio waves and analyzing their reflections. Unlike optical sensors (e.g., cameras), radar operates effectively in darkness, fog, rain, dust, and smoke, making it critical for all-weather missions.
Key Features & Functions:

Sensing Capabilities:

Obstacle Detection: Identifies terrain, buildings, power lines, and other aircraft.

Terrain Mapping: Generates high-resolution 3D maps using Synthetic Aperture Radar (SAR).

Altitude Measurement: Radar altimeters ensure precise low-altitude flight.

Motion Tracking: Doppler radar detects moving objects (e.g., vehicles, humans).

Technical Approaches:

FMCW (Frequency-Modulated Continuous Wave): Common for small drones; lightweight, low-power, and accurate for short-to-medium ranges.

Pulse Radar: Used in larger UAVs for long-range surveillance (e.g., military reconnaissance).

Millimeter-Wave (mmWave): Balances resolution and penetration (e.g., 24 GHz, 77 GHz bands).
