JIYI Back Obstacle Avoidance Radar Sensor - 24GHz Millimeter Wave Rear Protection Module for Agriculture Spraying Drone

The JIYI Back Obstacle Avoidance Radar Sensor provides modern agricultural spraying systems with comprehensive spatial awareness, effectively eliminating rear-facing blind spots during autonomous grid sorties. Utilizing high-penetration 24GHz millimeter wave technology, this specialized rear tracking module pierces through dense pesticide drift, thick field dust, and low-light environments that typically blind traditional optical sensors. By mounting directly to the rear alignment bracket of the multirotor chassis, it constantly reports the clear status of the backward flight path, preventing expensive hardware collisions with unexpected power lines, trees, or fencing networks.

Key Features :

• Advanced 24GHz Microwave Core: Employs high-frequency electromagnetic radar sweeps that safely ignore floating water droplets, dense spray mist, and field debris.

• Extended 30-Meter Scanning Zone: Continuously maps physical structural hazards up to 30 meters out, providing ample space buffers for automated electronic deceleration.

• Rugged IP67 Liquid Isolation: Fully sealed against corrosive chemical sprays, early morning moisture drops, and fine dust entry common to agricultural environments.

• Adaptive Dynamic Braking Links: Communicates directly over the high-speed system bus to command immediate autonomous stopping and hovering routines when objects cross proximity limits.

Use Cases :

• Real-time rear spatial obstacle monitoring for high-capacity 10L to 30L agricultural liquid spraying and dry seed spreading multirotors.

• Fail-safe path protection loops during automated cross-field return-to-home profiles when facing opposite orientation frames.

• Close-range precision trajectory buffer scanning across high-density fruit orchards, uneven tree rows, and complex electric grid lines.

Technical Specifications :

Compatibility Information :

This rear radar module interfaces flawlessly with professional JIYI flight ecosystem hubs. The hardware links directly into the dedicated radar port expansion sockets found on the K3A Pro and K++ power distributions. It works perfectly alongside existing down-facing terrain-following radars, providing full multi-directional sensory telemetry via the official JIYI Agri Assistant configuration tool.

Frequently Ask Questions :

Q1 ) What structural benefits does the 24GHz microwave frequency bring over standard sonar or optical sensors?

Ans : Sonar and optical systems degrade rapidly when exposed to thick airborne particles, changing ambient sunlight, or wet chemical clouds. The 24GHz millimeter wave signal effortlessly passes right through micro liquid spray droplets and heavy field dust to bounce directly off hard objects, preventing false braking triggers.

Q2 ) Can this rear radar unit be used as a downward terrain-following sensor to maintain altitude?

Ans : No, the back obstacle radar is configured with a specialized horizontal internal antenna alignment meant to scan for obstacles behind the moving multirotor. For automated altitude adjustment over crops, you must mount a dedicated downward JIYI terrain radar alongside this rear safety sensor.

Q3 ) How does the integrated electronic braking override protect the multirotor during a fail-safe mission?

Ans : When the back module detects a hazard like a utility pole within the preset caution barrier (adjustable via app settings), it flags the telemetry stream. The JIYI flight controller automatically halts manual or waypoint travel, engaging the motor braking loops to lock the drone into a safe, static hover.

Q4 ) Is the JIYI back obstacle radar good for beginners?

Ans : Yes, it is highly optimized for beginner fixed-wing and multirotor commercial operators who are managing large agricultural layouts. The automated 30-meter detection buffer, simple plug-and-play connection, and dynamic obstacle braking provide a critical layer of safety during early autonomous pilot training.

Q5 ) How far can this micro RC airplane radar track physical objects accurately at the field site?

Ans : The integrated high-frequency transceiver provides a reliable distance measuring envelope stretching from 1.50 meters up to 30 meters in clear open flight corridors. This gives the autopilot computer plenty of distance overhead to comfortably decelerate and secure a hover before contacting the target.
