LDRA100 24GHz Radar Drone Altimeter FMCW Radar

The LDRA100 is a radar that can be used for height measurement of unmanned aerial vehicles (UAVs). It operates on the 24GHz-ISM frequency band and has extremely strong anti-interference capabilities, making it suitable for harsh environments such as rain, snow, fog, and dust.

  • Super Light Weight <20g : Mini compact size, no burden on drone load and flight endurance.
  • High Precision Altitude Measurement ±1cm : Stable height locking, smooth hovering and safe takeoff & landing.
  • All-Weather Working IP67 Waterproof : Not affected by light, fog, dust, dark night; normal operation in complex outdoor environment.
  • Low Power & Easy Compatibility : Ultra-low power consumption <1.5W, support UART/I2C interface, plug and play with Pixhawk, ArduPilot and mainstream flight controllers.
  • Plug & Play with Pixhawk/ArduPilot:Pre-configured for major flight controllers. UART/I2C/CAN interfaces, sample code and integration guide provided.

Application

  • Agricultural plant protection drone fixed height cruise
  • Indoor / outdoor inspection drone height holding
  • Consumer aerial photography drone landing assist
  • Light logistics delivery drone altitude monitoring
Is it compatible with Pixhawk 4 / Cube Orange?
Yes. The LDRA100 supports UART, I2C, and CAN interfaces. We provide integration guide and demo code for PX4 and ArduPilot-based flight controllers.
Can it be used for both altitude hold and obstacle avoidance?
It is primarily designed for precision altitude measurement. For forward obstacle avoidance, please see our LDMR220 77GHz radar.
How does it perform in rain or dust?
The IP67 rating and FMCW modulation ensure reliable operation in rain, snow, fog, and dusty environments where ultrasonic or optical sensors fail.
What is the weight impact on a small drone?
At <20g (including harness), it adds minimal payload, making it suitable for small consumer drones as well as industrial UAVs.
