What Is Jiyi Front Obstacle Radar
The Jiyi Front Obstacle Radar is a compact radar sensor module designed for drones (particularly agricultural or UAV drones) to stumble on limitations in advance and assist keep away from collisions.
Key technical specifications that outline it:
It operates at a centre frequency of 24.125 GHz.
The radar uses the modulation approach called FMCW — Frequency-Modulated Continuous Wave — to ship and acquire radar indicators.
It has a detection (ranging) functionality from about 1 meter as much as ~25 meters, with normal accuracy round 0.1 m and resolution about 0.6 m.
Physical length/weight: roughly sixty six×66×19.5 mm and about eighty g — small and light-weight enough for drone mounting.
How FMCW Radar Works (in This Context)
The underlying technology — Frequency-Modulated Continuous Wave (FMCW) — is vital to how the radar detects limitations. Here’s a simplified clarification:
The radar continuously transmits radio waves whose frequency is various (modulated) through the years (the “chirp”). When those waves hit an item (tree, cord, pole, individual and so forth.), they reflect again.
The radar’s receiver captures the contemplated signal. Because the transmitted wave’s frequency changes through the years, the reflected wave’s frequency will be barely different relying on how a long way away the item is (due to the time delay).
By comparing the frequency difference among transmitted and acquired signals, the radar calculates the distance (variety) to the impediment. This presents actual-time measurements of the way a long way away limitations are.
FMCW radar also frequently helps non-stop scanning and may refresh measurements regularly (e.G. Tens of instances in step with 2d), enabling dynamic detection because the drone moves. This ensures the drone can discover barriers even at excessive velocity and modify its flight course in time.
Because the radar uses radio/microwave waves as opposed to visible mild or infrared, its performance remains strong in bad lighting fixtures, high dirt, fog, glare or even at night — situations in which visual cameras / optical sensors might fail. The makers of the Jiyi radar explicitly observe this “all-climate, all-surroundings” operation functionality.
Jiyi Radar has a number of essential features that allow it to excel at identifying small and mid-sized obstacles; it can locate and avoid them like no other technology available similar to Jiyi Radar. Obstacles identified using Jiyi Radar’s unique design and capabilities include:
Thin electric wires and cables (which are very, very hard to detect with cameras). In addition, when viewing at a distance or in busy areas with many items in sight: it is almost impossible for cameras to identify thin wires.
Small tree trunks/trunks (approximately 10 centimetres in diameter), as drones fly lower in proximity to trees or groups of tree limbs.
Poles, posts, fences, irrigation structures, many types of farm equipment and all other places where most of these types of objects will be found. A small pole (approximately 15 cm tall) can easily be seen by Jiyi Radar. The radar will detect almost every type of pole in an area.
Any person or unexpected object(s). In particular, anything standing in the flight path of a drone would be a very big issue.
Drones used in agriculture (crop-spraying, field mapping) or for anything outside will have significant advantages from Jiyi Radar’s ability to detect obstacles. With the detection of obstacles, it is possible to eliminate many accidents and to protect sensitive equipment and the payload of a drone. Additionally, Jiyi Radar provides the capability to perform flights at a safer level, even when flying in very poor conditions (dust, foggy, dusk, etc.).
Lastly, Jiyi Radar offers a real-time readout of the distance to the obstacle, which can be translated by the flight controller into automatic maneuvers for collision avoidance or for coverage of exposure to the object in question.
Several features of the Jiyi front obstacle radar make it an ideal option for drones used within various industries, such as the agricultural industry, to spray herbicides and pesticides, and use for mapping and surveying operations.
Compact, Lightweight Design:
Weighing approximately 80 grams, and its small size does not add significant weight to the payload of the aircraft (which can impact flight performance), and therefore makes it easier to fly efficiently and maintain a stable flight during operation.
Robust, All-Weather Radar Sensing:
The Jiyi’s sensor system can provide information to the operator without regard to lighting conditions, dust, fog, or any other environment associated with field operations.
Excellent Range and Accuracy:
The Jiyi provides a safe margin of distance from 1 to 25 m, with a detection range of 0.1 m. This allows the operator to provide the drone additional time and space to adjust its flight path to avoid obstacles.
Easy to Integrate: The Jiyi uses commonly used radar interfaces (e.g., CAN) and a standard electrical connection to provide power to the sensor. These interfaces allow a seamless interface with the majority of standard drone flight controllers and associated electronics systems.
