Drone radar sensor have become a key element in the safe and intelligent operation of UAVs. As the use of drones in agriculture, industrial inspection, surveillance, and mapping grows at an incredible rate the demand for which they perform a reliable obstacle detection has become primary. A drone radar sensor enables unmanned aerial vehicles in real time to see out other aircraft and objects, and to operate safely in very complex and undefined environments.
At Bharat Skytech we focus on the development and sale of professional grade agriculture drones and advanced UAV electronics which include high performance radar sensors for precise obstacle avoidance
What is a drone radar sensor?
A drone radar sensor which is an electronic device which uses radio waves to identify objects in the drone’s flight path. As opposed to optical sensors that use cameras or light detection radar sensors do well in:
- Poor visibility conditions.
- Weary agricultural fields.
- Fog and drizzle.
- Night time operations.
- Bright sunlight conditions.
Radar systems transmit radio frequency waves which they also use to determine the distance, speed, and location of objects.
Why do we use drone radar sensors in agriculture drones?
Agricultural drones work in ever changing and uncertain environments.
In fields we see:
- Forests.
- Electric towers.
- Cables.
- Farm buildings.
- Variable topography.
- Dynamic obstacles.
Without the proper obstacle detection the risk of collision goes up. A drone radar sensor which:
- Auto obstacle detection.
- Instant response.
- Improved flight performance.
- Reduced chance of crash.
- Increased operation efficiency.
- Improved pilot safety.
For large scale spray tasks radar sensors in drones are a must.
How Drone Detection Radars Function.
Drone radars use radio frequency transmission and return information. The process includes:
- The radio wave section of the system puts out electromagnetic waves.
- Waves break at the barrier.
- Refracted waves back to the sensor.
- The system measures distance and position.
- The flight control system which in turn modifies the drone’s movement.
In the span of milliseconds this process takes place which in turn enables real time obstacle avoidance.
Types of Drone Radar Sensors
1. Forward Radar
Detects obstacles in front of the drone during forward motion.
2. Rear Radar
Detects objects behind the drone during reverse movement or braking.
3. Multi-Directional Radar
Covers front, back, sides, and sometimes downward detection for full obstacle awareness.
For agriculture drone systems, integrating both front and rear radar provides maximum operational safety.

Drone radar systems report into the flight control board constantly. At which point an obstacle is detected:
- Distance info is sent out at once.
- The system determines risk of collision.
- The drone decreases speed, stops, or changes course.
This smart automation which in turn decreases pilot response time and improves operational safety.
