A Doppler radar is a type of radar system which uses Doppler effects to determine an object’s velocity data from distance. This is done by the bouncing of microwave signals off the target and determines how the object’s motion alters the frequency of returned signals. Advantages: 1. High-quality data: Doppler radar provides high-quality data compared …
When it comes to buying a radar detector, most people think that the more expensive is better. Many times this is true, but not always. You will need an accurate radar detector that will precisely locate the signal and then warn you of its presence. What Factors to Look for in a Radar Detector? It …
Lidar drone sensors capture imagery and provide drone operators with accurate 3D mapping instantly. A few years ago to get the same imagery, a large aircraft with heavy Lidar sensors was used. Lidar sensors are becoming increasingly diverse and drone technology keeps on changing so are the sensors. By buying the latest commercial drones …
Image source: impossiblegeology.net Geologists use LIDAR to see and study the earth’s surface mostly in areas where trees and vegetation obscure the earth’s landscape. The Lidar system (light detection and ranging) uses pulses of light to collect 3D information. An airplane using a laser system pointed at the ground can collect Lidar data which is …
Image source: remote-sensing-biodiversity.org Lidar remote sensing technology uses light pulses to detect an object’s distance. It uses light pulses to measure the distance by illuminating a target with a laser beam and analyze the reflected light. Remote sensing and Lidar systems (Light detection and ranging) provide invaluable data used in different geoscience applications. The technology …
Image source: extremetech.com Lidar systems and depth cameras have become part of today’s depth-sensors in the digital market. The sensors supplement the current monocular RGB images by providing per-pixel depth information of the target objects. The depth- sensors accurately measure the distance and wavelength of a target object and return a 3D representation. Although the …

Lidar and photogrammetry technologies are almost similar but different at the same time based on the techniques used. Lidar is a light detection and ranging technology that uses laser beams. Photogrammetry transforms the 2D images into 3D models. Lidar and photogrammetry have different use cases with different conditions and deliverables. The two technologies offer fast …
LiDAR technology, which stands for Light Detection and Ranging, uses light to map virtually any kind of physical environment. Extremely accurate images can be rendered due to LiDAR technology’s use of very precise laser beams. It is a Remote Sensing technique, using either ground-based (Terrestrial Laser Scanning (TLS)) or airborne systems (Airborne Laser Scanning (ALS)), …
Advantages of Lidar Scanning in Archeology Lidar is the best choice for many different applications, including archaeology. The lidar wavelength is approximately half a micron(one micron equals 1/25,000 of an inch), much smaller than say radar wavelengths (which are in centimeters or decimeters). For ground details big and small, lidar easily wins over radar. Lidar …
Marine radar is an essential tool for every onboard ship to navigate safely. The radar enables the ship to detect, track and position targets as it navigates from one point to another. Radar systems can be used in a variety of ways and the list below explains the uses of radar technology in the marine …
