Dection Mode - PD150 particulate matter liDAR
PP1 Scanning
PPI stands for Plan Position Indicator. The center point is the lidar antenna, which displays the distance and echo in-tensity of the target object when scanning at a constant pitch angle and azimuth angle for one cycle or a specific angle. It is commonly used in various lidar displays in the fields of air traffic control, marine navigation, and meteorology.
CAPPI scanning
CAPPI stands for Constant Altitude Plan Position Indicator, which is a variant of PPI that uses PPI data from multiple pitch angles to obtain horizontal cross-section echo data at the same altitude. It is commonly used in meteorological lidar.
RHI scanning
RHI stands for Range Height Indicator, which is used to obtain the target distance and echo intensity under the constant azimuth angle and pitch angle scanning, and display them.
THI detection
THI stands for Time Height Indication, which can carry out continuous observation in the vertical direction at fixed points. Through long-term continuous observation, the continuous change of aerosols from surface to high altitude in the area, and the fluctuation of the boundary layer can be obtained.
Mobile observation
Mobile Observation, based on the vehicle-mounted lidar system, can not only quickly detect the source, spatial distribution, transmission path, and sudden events of atmospheric particulate matter, but also has high spatial resolution. Therefore, it can be an effective supplement to ground-based, airborne, and spaceborne lidar detection, achieving 3D detection of particulate matter within the area.
Applications of 3D Particulate Matters Detection LiDAR
Air quality monitoring field
The air pollution in Chinese cities is mainly caused by bituminous coal from industrial enterprises, heating boilers, transportation, etc. In accordance with China’s relevant environmental laws and regulations, although most polluting enterprises have installed online monitoring equipment as required to monitor the concentration of pollution discharge, there are still problems such as pollution sources being geographically dispersed and some enterprises not installing monitoring equipment for stealing discharge at night. Air quality monitoring sites based on ground-based remote sensing technology can measure the continuous point source particulate matter concentration, but the number of sites is limited and regional representativeness is poor. Lidar technology is a new active remote sensing tool for detecting atmospheric particulate matter. Portable particulate matter lidar has the advantages of wide range, high precision, and stable performance in the air quality monitoring field, making it more suitable for long-term and unmanned monitoring. PD150 lidar can use vertical and horizontal scanning observation methods to detect the atmosphere, monitoring the large-scale pollution areas.
