Previously, sensing technologies that have been used in the presence of obscurants include RADAR based sensors53,54, and passive sensors based on thermal imaging55,56. There has been some previous work on using LiDAR for imaging through obscurants, but this was mostly laboratory-based work or ...

Among these sensors, LiDAR has received widespread attention owing to its high resolution, accuracy, and ability to generate three-dimensional maps, as well as the fact that it is not as affected by rain and fog, in contrast to radar and cameras [4]. The principle of LiDAR sensors is ...
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...
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]. ...
