2022-05-26
Agricultural UAV detection radar will face complex environment or challenges in the process of operation. For example, farmland often has obstacles, such as trees, utility poles, houses, animals, and other things that suddenly appear. At the same time, because the agricultural UAV flight height is generally 2-3 meters above the ground, the UAV detection radar is easy to mistakenly identify the ground as an obstacle.

For example, farmland often has obstacles, such as trees, utility poles, houses, animals, and other things that suddenly appear. At the same time, because the agricultural UAV flight height is generally 2-3 meters above the ground, the UAV detection radar is easy to mistakenly identify the ground as an obstacle.
This puts forward high requirements for agricultural UAV detection radar, which requires strong resolution and sensitivity to detect obstacles in farmland. new agriculturalUAV detection radarEquipped with a 4D imaging radar system, it provides nanny-level flight guarantee for drones and brings users a more stable operating experience.
Thanks to the new UAV detection radar system-4D imaging radar and ground-like radar,UAV detection radarIt has all-round environmental perception and ground-like flight capabilities, can accurately perceive the location, distance, moving direction and speed of obstacles within a range of 40 meters, automatically predict and smoothly bypass obstacles in farmland, and realize autonomous operations in different scenarios such as mountains, hills, plains, fruit forests, etc.
There are usually two factors that affect obstacle recognition: reflection cross-sectional area and reflectivity. The reflection cross-sectional area can be understood as the larger the surface area, the easier it is to find obstacles. The reflectivity mainly depends on the material of the obstacle. The reflectivity of metal is high, while the reflectivity of plastic foam is low, and radar is not easy to effectively identify such obstacles.
A radar that can be used conveniently in farmland requires a strong resolution and can accurately find obstacles in complex terrain environments. This is determined by the radar antenna. In addition, it requires high detection sensitivity, even small objects can be found.
UAV detection radarThe carried 4D imaging radar is a vehicle-gauge-class millimeter-wave radar with a radar antenna array that can send and receive millimeter waves in both horizontal and vertical directions, and a gimbal that can swing in real time. The traditional millimeter wave radar only has the ability to perceive obstacles in the horizontal direction, and even if the 360-degree rotation mode is added, the perception in the vertical direction may not be clear.
The new 4D imaging radar has an especially vertical antenna, which has the ability to sense vertical obstacles in the environment. The addition of the swing gimbal also increases the recognition range of the radar, swaying up and down during the work process, covering the range of the drone's flight direction from 45 degrees downward to 90 degrees upward. Combined with the down-looking ground simulation radar, it provides all-round protection for the UAV in the process of moving forward, and provides users with a more stable and reliable flight experience.
