24Ghz Radar MAX 4T and 60Ghz Radar MAX 4T Description
Autel MAX 4T is the first commercial drone with a millimeter-wave radar sensor. The millimeter-wave radar technology can be used to improve the drone's obstacle avoidance effect and improve its perception ability. In the millimeter wave radar sensor of Autel MAX 4T, there are two versions, one is a 24Ghz radar sensor, and the other is a 60Ghz radar sensor.
24Ghz radar and 60Ghz radar obstacle avoidance instructions
When the millimeter-wave radar sensor of Autel MAX 4T is 24Ghz, the drone only has downward-looking radar. Therefore, at night, the obstacle avoidance will indicate that the obstacle avoidance fails due to insufficient light. You should try to fly in a place with sufficient light.
When the millimeter-wave radar sensor of Autel MAX 4T is 60Ghz, the drone has front-to-back, up-down millimeter-wave radar, and the obstacle avoidance function takes effect no matter it is day or night.
24Ghz Radar and 60Ghz Radar Specifications
| Frequency |
60GHz/24GHz* *Please fly safely and comply with your local laws and regulations to use 60GHz. |
| Sensing Range |
60GHz Radar: Upward: 0.98-787.4in (0.3-20m) Downward: 5.9-3149.6in (0.15-80m) Forward and Backward: 0.98-98.43ft (0.3-50m) 24GHz Radar: Downward: 2.62-39.4ft (0.8-12m) |
| FOV |
Horizontal (6dB): ±60°/±22° (24G/60G) Vertical (6dB): ±30°/±20° (24G/60G) |
| Operating Environment |
The 60GHz millimeter-wave radar sensing system supports all-weather obstacle avoidance for glass, water, wires, buildings, and trees. Its obstacle avoidance distance varies with the obstacle's ability to reflect electromagnetic waves and its surface size. The 24Ghz millimeter-wave radar supports downward sensing, and its sensing range varies by the ground material. For example, the sensing range of cement ground is 12 meters, and the sensing range of grass with a thickness of more than 3cm is less than 6 meters. |
In practical applications, 24GHz is suitable for outdoor tasks requiring distance and penetration; 60GHz is more suitable for high-precision, privacy-friendly close-range scenarios.
Note: According to relevant laws and regulations, countries such as China and South Korea only permit the use of downward-facing 24G radar (i.e., millimeter-wave radar installed on the underside of the aircraft for downward detection). For specific usage requirements, please refer to the laws and regulations of the respective country.
