The Different Types of LiDAR Systems

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…


Why do submarines use sonar instead of radar

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…


Top 10 LiDAR Companies in India 

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…


Optical Imagery Vs Radar Sensing – Is One Better?

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…


Advantages of LiDAR in Self-Driving Cars

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…


How does Lidar see through trees

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…


Lidar VS Radar VS Camera

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 vs. Pulsed Doppler vs. Phased Array vs. PESA Radar

AESA vs. Pulsed Doppler vs. Phased Array vs. PESA Radar

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…


Active Radar vs. Passive Radar

Radar (Radio Detecting and Ranging) systems and systems that are designed to detect objects and to evaluate the distance between the objects and a single antenna or a group of antennas. Both active and passive radars have advantages, and people prefer using either of them for different reasons. As they have advantages, they also have…

Radar detectors

Pros and Cons of Radar detectors

These are devices that are bought to detect radio waves. As a matter of fact, radar detectors detect radio waves in a range of wavelengths X, K, Ka, and Ku. Today, these devices have seen many uses. In some cases, they are used to inform motorists about speed traps and radar guns. In some other…
