What are two advantages of radar over lidar?

Radar offers several unique advantages over lidar, with better performance in adverse weather and longer range capabilities being two of the most significant.

Radar systems utilize radio waves to detect objects, which allows them to penetrate through adverse weather conditions such as fog, rain, and snow. This capability is crucial for reliable operation in various environmental challenges, where lidar's reliance on light can be significantly hindered. Consequently, radar systems maintain functionality where visibility is compromised, making them exceptionally valuable for applications like automotive safety and aviation.

Additionally, radar has inherently longer range capabilities compared to lidar. The nature of electromagnetic waves used in radar enables effective detection of objects at greater distances. This attribute is particularly advantageous in scenarios like traffic monitoring and surveillance, where understanding the environment from a distance is essential.

While the other options touch on different aspects of technology, such as cost and energy efficiency, they do not accurately encapsulate the core advantages of radar over lidar in the context of performance during adverse conditions and range.
