Years ago, marine radars were only mounted on large boats operated by seasoned sailors. They used to be bulky and not always compatible with the average systems used on boats. These days, even amateur sailors on smaller boats with relatively basic systems can easily avail of lighter, system friendly versions of marine radars to help …
Yes, lidar can penetrate water but can be quite a challenge. Mainly due to various limitations such as refraction and light absorption. Greenlight (infrared wavelength of 532nm) from Lidar sensors can penetrate water the best and farthest due to its wavelength. It can penetrate ocean water of up to hundreds of meters (up to 300m). …
Remote sensing, surveying, and monitoring have, in the last few years, reached new heights with the power of the LiDAR technology. The proliferation of LiDAR, which stands for Light Detection and Ranging, is now seen in multiple industries including forestry, disaster management, weather prediction, construction, archaeology, autonomous vehicles, and many more. It is important to …
Submarines were first built in the 19th century and rose to popularity during the First World War. The extraordinary capability of these vessels to remain beneath the surface of the water for long periods and enter enemy waters undetected made them indispensable in warfare. Apart from the navy, submarines have also found their use in …
As the world continues to advance in the latest surveying and monitoring technologies based on LiDAR (Light Detection and Ranging), there is a huge potential of applying these technologies on the diverse terrain of India. Although earlier there were challenges for Indian companies to invest in the LiDAR technology, given stringent regulations on capturing aerial …
The ability to view the details of the surface of the earth from satellites has come a long way, thanks to rapid advancements in technology over the last few decades. Everyone with a smartphone now can “see” an image of their neighborhood through Google Maps. But applications of fetching images of earth surfaces go way …
Optical Imagery Vs Radar Sensing – Is One Better? Read More »
Self-driven cars are no longer a component of science-fiction stories. They have been under development for years and have already hit a few roads in the US under testing conditions. A large number of advanced technologies have gone into building the version of autonomous cars that we see today, of which, LiDAR is one of …
Surveying and mapping technologies have come a long way in the last few years, of which one is LiDAR. LiDAR stands for Light Detection and Ranging and is used to locate objects and their positions based on how far it is from the light-emitting source. As the name suggests, a light source is used to …
In the modern age, humans have started drifting away from not relying too much on their eyes and side mirrors to drive their vehicles anymore. Autonomous or self-driving vehicles have started taking the world by storm and are the future. It is common knowledge that top car manufacturing companies like Telsa and Waymo have embraced …
AESA Radar vs. Pulsed Doppler Technological advancements in the 1980s resulted in the invention of the Pulse-Doppler radar which had the capabilities of tracking while scanning. This feature enabled the radar to track specific targets, while also being alert for the possible entry of other objects. The bad news is that pulse-Doppler radars are also …
