Learn how radar and LIDAR are different, and why you should care. You might be surprised as we dispell some common myths.
I am asked to delineate between UAV and UAS. Previously I would have thought of UAS as the air vehicle and the controlling hardware/software only. But after this week I’ve learned that the system may also include ground-based radar systems, air-...
The Radar captures and automatically tracks signals transmitted from a radiosonde attached to a balloon to obtain atmospheric conditions, calculating wind direction and wind velocity while the balloon is being uplifted, and it inputs the received data along with angle data and time signal into the ...

The LiDAR term is coined from radar and its adoption began with long-range applications such as terrestrial mapping. The LiDAR term tends to be associated with relatively long-range applications, such as autonomous driving, while the ToF camera or the ToF sensor term is more commonly used for ...
However, radar and hyperspectral imagery cannot be used to directly retrieve water depth, and photogrammetry requires very clear water conditions [3]. Meanwhile, their precision is relatively poor, and they cannot provide a high-resolution distribution (errors in the order of 1 m) [4–6]. ...
rTehnecaeccGuNraScSy odfatthaewere GNSS + IMU trajectory was determined by comparing the tree locations calculated from the total- station measurements with those measured from the point cloud [20]. Table 2 also shows the post- processed results of the NovAtel SPAN system. T45h9e6positioning ...
consisting of an active system to simultaneously measure the distance and intensity of every point in the scene, by monitoring the time between the emitted and received light pulse, usually called by Time of Flight (ToF), using the same principle as radio detection and ranging (RADAR), develope...
