What is the difference between Lidar and Radar?

While Lidar and Radar use similar technologies and approaches to tracking and moving objects, there are differences in how every technology works and types of applications for which everyone can be best used. Both technologies use energy reflected from objects to determine different aspects of these objects, but the types of energy used in each of them are different. The types of objects that can be precisely placed and measured through Lidar and radar also differ in size and nature. In Lidar and radar, energy transfer is sent from the source as a signal. When the signal hits the object, this object then reflects part of the energy from the original signal. This reflected energy is then accepted at the site of the source and is used to determine the distance, size and other attributes of the object.

While both Lidar and radar use the same technique, the radar was the first form of this technology and is still used for certain applications. A radar that means "detection and extent of radio" sends energy pulses relativelyLarge wavelengths using radio waves. When these radio waves are reflected, the received signal can be used to determine the various aspects of the reflecting object. The size can usually be set relatively well, as well as the position of the object and the Doppler shift of reflected radio waves can be used to determine the speed and direction in which the object moves.

Lidar, which means "detection and extent of light", is an alternative form of technology used in the radar to determine the location and orientation of the object or objects. Lidar uses energy with smaller wavelengths, such as ultraviolet energy for the source signal. These smaller wavelength signals are crashed back by smaller objects than is usually detected through a radar, so Lidar can be used to detect very small objects such as dust particles or various aspects of different weather and atmospheric phenomena. As a result, Lidar is a better choice for studying weather patterns using relatively small technology, which is particularly useful for study remoteatmosphere through satellites orbiting other planets.
