JIYI Terrain Ground Radar Sensor - Millimeter Wave Alt Following Module for Agricultural Drones

The JIYI Terrain Ground Radar Sensor provides industrial drone operators with a bulletproof altitude-following system designed to optimize autonomous crop-spraying and topographic monitoring paths.

Precision 24GHz Millimeter-Wave Alt Following :

Conventional optical flow modules or sonar height sensors struggle heavily over dense crops, dusty fields, or changing light conditions. JIYI avoids these sensor limitations by incorporating a high-frequency 24GHz millimeter-wave radar array. This professional radar signal penetrates floating chemical mist, surface dust, and dense crop leaves effortlessly to bounce cleanly off the real solid ground below, maintaining a highly stable altitude reading.

Fully Autonomous Topographic Profile Tracking :

When mapping or spraying hillside orchards or uneven terrace fields, maintaining a manually uniform distance to the crop canopy is nearly impossible. This module continuously tracks ground slopes at millisecond speeds, feeding live altitude adjustments straight to your flight controller. This allows your multirotor to climb and descend gracefully along the natural landscape, protecting your chemical footprint while ensuring high drone safety.

Sealed All-Weather IP67 Shell Engineering :

Agricultural spraying environments expose onboard electronics to intense moisture, highly corrosive pesticides, and fine soil dust. The sensor hardware is completely encased within a rugged, hermetically sealed IP67 waterproof outer casing. This durable construction shields the core internal radar circuits from long-term liquid corrosion and ingress failures, maximizing field lifespan.

Frequently Asked Questions :

Q1: How does this terrain radar module plug into my JIYI K3A Pro or K++ flight controller?

Ans: The module features a dedicated connection cable that interfaces directly with the CAN port or marked radar sockets on your JIYI flight controller hub. Once connected, open the JIYI Agri assistant software or ground control app to activate the radar function, verify the altitude readings, and configure your target canopy following heights.

Q2: Will the radar module register false ground height metrics when flying over dense tall weeds?

Ans: No. Unlike basic laser altimeters that get tripped up by the top layer of leaves, the 24GHz millimeter-wave signals are optimized to pass right through thin foliage and crop canopies. It calculates its returns based on the hard soil surface underneath, giving your drone a true ground relative altitude.

Q3: Can I run this terrain following sensor simultaneously with a JIYI obstacle avoidance radar?

Ans: Yes, absolutely. JIYI's advanced autopilot frameworks are designed to manage multiple radar arrays at the same time. You can mount this terrain sensor facing straight down for automated altitude management, while attaching the obstacle avoidance radar facing forward to scan for power lines, trees, and field boundaries.

Q4: Does the radar casing require regular cleaning to preserve its sensing range?

Ans: Because millimeter-wave radar signals pass easily through non-metallic blockages, light coats of dust or chemical spray droplets on the shell won't affect its accuracy. However, to prevent heavy chemical build-up and protect the plastic shell over time, we suggest wiping the face plate with a clean cloth after daily operations.
