UAV detection radar works by sending laser pulses in rapid succession in a series of precisely defined directions. Measuring the travel time of each laser pulse reflected from the target and returned to the lidar scanner can reconstruct the distance and direction of the surface around the scanner. Connecting a lidar scanner to a mobile platform like a UAV allows 3D mapping of a larger surface area as the UAV platform moves forward.
UAV detection radarThe principle of operation is to send laser pulses in a series of accurately defined directions in rapid succession. Measuring the travel time of each laser pulse reflected from the target and returned to the lidar scanner can reconstruct the distance and direction of the surface around the scanner. Connecting a lidar scanner to a mobile platform like a UAV allows 3D mapping of a larger surface area as the UAV platform moves forward.
UAV detection radarApplication areas:
1. Accident scene
Lidar is an active system that uses ultraviolet and near-infrared light to image objects that do not require external light for effective mapping. For example, when monitoring intercontinental accumulations at night, it is easy to deploy drones equipped with lidar and pass through the site in a single pass.
As a drone-based solution, accurate information with visible details can be returned immediately, which can then be accepted as evidence in court. On the ground, wreckers and sanitation workers can jump-start the cleanup process, saving thousands or even millions of dollars by freeing up commuters and reducing the cost of accident personnel.
2. Agricultural and forestry surveys
Forests are huge, and managing these vast areas can be overwhelming. Traditional forest inventory assessment methods are time-consuming and inefficient, and sometimes only a rough estimate of a large area. Equipped with lidar drones, foresters can measure canopy height, cover, tree density, and even the location and height of individual trees. This eliminates the inaccuracies and inefficiencies of conventional methods. The additional benefit of lidar is that it can make these measurements even if the human eye cannot because they do not rely on natural light for operation.UAV detection radarCanopy height and tree density can be measured.
3. Agriculture and Gardens
In large farms, three-dimensional landscape mapping has become the key to implementing effective irrigation systems. For example, for large-scale rice planting, farmers need to build dams, which requires an accurate understanding of the terrain for the dam system to function. Equipped with LidarUAV detection radarData can be collected once.
4. Terrain Modeling
Compared with traditional ground measurement methods, laser radar can save significant costs. Using the method of detecting distant objects (such as leaves, shrubs, trees and even grass), lidar can determine their position, speed and other characteristics by analyzing the pulsed laser light reflected from the surface of objects. It provides a three-dimensional terrain contour model that a ground operator can work.
5. Power line inspection
You can extract detailed information about the distance between power lines and electrodes from the point cloud. This allows surveyors to analyze the detailed structure of the power line corridor, including vegetation, roads and houses, and identify potential risks.
6. Topographic and bathymetric measurements
Topographic and bathymetric surveys usually cover large areas of terrain and are usually carried out by aircraft and helicopters. The terrain lidar uses near-infrared lasers to map the land, while the bathymetric lidar uses permeable green light to measure the seafloor and river bed.
7. Archaeology
In the past, traditional surveying methods for large historic sites took years to complete, but now with the help of new lidar technology, entire cities can be mapped in 3D in minutes.
8. Mine Surveying
Due to the complex terrain of the mine, the use of total station, GPS and other traditional measurement methods for high-precision surveying and mapping is often time-consuming and laborious. Especially with the introduction of the concept of digital mine, the need for spatial three-dimensional information in mine management is more urgent. 3D visualization management mode has become one of the main contents of digital mine, but the data obtained by conventional measurement methods is difficult to meet the needs of 3D digital mine. In recent years, the rapid development of 3D laser scanning technology andUAV detection radarIt provides a new technical means to solve the complex mine topographic survey and digital mine construction. Laser radar technology has the advantages of high resolution, high sampling rate and non-contact measurement, which is very suitable for obtaining the spatial three-dimensional information of complex surface and high-risk areas of mines.
