Product Details
Jiyi Obstacle Avoidance Radar for Agriculture Drones (UAV-R21-F) – Forward Radar
Product Overview
The Jiyi Obstacle Avoidance Radar (UAV-R21-F) is a forward-facing radar sensor designed to improve the safety and reliability of agricultural drone operations. Built using 77–81GHz FMCW radar technology, it provides accurate real-time obstacle detection, allowing UAVs to identify and avoid obstacles during spraying, mapping, inspection, and other autonomous flight missions.
Unlike camera-based obstacle detection systems, the Jiyi UAV-R21-F performs reliably in challenging environments such as fog, dust, low-light conditions, and bright sunlight. Its compact, lightweight design makes it suitable for integration into a wide range of agricultural UAV platforms while maintaining minimal impact on payload capacity.
Whether operating over crop fields, orchards, or uneven terrain, this radar helps improve flight safety, reduce collision risks, and support smoother autonomous operations.
