Three-beam Doppler lidar is a type of lidar system that uses a laser beam to measure the distance and velocity between an object and the radar. This radar system is often used in meteorology, environmental monitoring, military reconnaissance, and other fields.
Three-beam Doppler lidar consists of three main components: a laser transmitter, a receiver, and a signal processing system. The laser emitter emits three laser beams of different wavelengths, which are reflected by the object and received by the receiver. Due to the object's motion relative to the radar, the reflected light waves undergo a Doppler shift, which can be measured and used to calculate the object's velocity.
The advantages of three-beam Doppler lidar include high accuracy, high resolution, and high sensitivity. It can work at different distances and speeds, and it can measure the three-dimensional motion trajectory of objects. In addition, because lidar uses light waves, it can penetrate some substances that are opaque to microwaves and radio waves.
Three-beam Doppler lidar has a wide range of applications in several fields, such as the following:
Navigation and positioning: Three-beam Doppler lidar can be used in vehicle navigation systems, which can continuously measure navigation parameters such as the three-dimensional axial velocity and instantaneous position of the vehicle relative to the ground to achieve autonomous navigation.
Intelligent transportation: In the field of intelligent vehicles, Doppler lidar technology can obtain information such as the speed and direction of movement of target objects, so as to quickly and accurately detect surrounding vehicles and obstacles, and take countermeasures such as avoidance and emergency braking to avoid accidents such as rear-end collisions and collisions.
Autonomous driving: Doppler lidar technology can also monitor vehicle wheel speed, steering angle and other parameters in real time, providing important support for autonomous driving technology.
Meteorology and environmental monitoring: Three-beam Doppler lidar is also used in meteorological research and environmental monitoring, and can obtain information about meteorology and the environment by measuring the reflection and scattering of laser light in clouds and particles in the atmosphere.
Military reconnaissance: In the military field, three-beam Doppler lidar can be used for reconnaissance and target identification, and by analyzing the reflected light waves, information such as the shape, speed, and distance of the target can be obtained.
Three-beam Doppler lidar is a very useful lidar system that can provide high-precision and high-resolution measurements, and can work in different environments and conditions.
LiDAR reflectors are an important part of a three-beam Doppler lidar system. Its main function is to reflect the laser beam emitted by the lidar, so that the laser beam can be returned to the radar receiver, so as to achieve distance and velocity measurement of the target object.
A three-beam Doppler lidar system measures the distance and velocity of a target object by emitting three laser beams of different wavelengths at the target object and receiving the reflected light signal. The presence of a reflector can enhance the strength of the returned signal, improving the accuracy and reliability of the measurement. The LiDAR calibration plate is stable and can obtain repeatable and accurate data. It is suitable for autonomous driving distance, marking test and remote sensing target and other fields, with a reflectivity of 1-99% optional, no powder and no yellowing, and nearly perfect Lambert characteristics. The diffuse reflector adopts an exclusive spraying process, which can provide a variety of reflective splicing diffuse reflectors for seamless splicing.
