Automotive radar and LiDAR sensors: one masterpiece and another in the makingRadar is a masterpiece of automotive safety systems, thanks to its efficiency, simplicity, and reliability, but LiDAR sensor technology still has some way to go to prove its efficiency and relevance.GUILLAUME GIRARDIN...
AUTOMOTIVE sensorsAutomotive radar and lidar sensors represent key components for next generation driver assistance functions (Jones, 2001). Today, their use is limited to comfort applications in premium segment vehicles although an evolution process towards more safety-oriented functions is taking place....
Multiple sensors can be configured together to provide high-resolution 360° detection under all weather and lighting conditions, enabling advanced applications such as parking assistance, lane change assistance and cyclist and pedestrian detection.

LiDAR由于波长较短,很容易收到空气介质中的各种杂质干扰。大气中的水分会影响LiDAR系统的性能,而且在恶劣天气下(比如雨雪雾天),LiDAR系统表现并不理想。较短的波长也容易发生信号衰减,在晴朗天气中,LiDAR的探测范围就小于Radar系统;而在恶劣天气中,LiDAR的感知范围会远小于Radar。下面四张图分别展示了自动驾驶场景的Radi...
简单介绍Radar(雷达)和Lidar(激光雷达)的区别 在看无人驾驶相关的资料时,发现关于radar和lidar分的很清,特在此做个简单的介绍以免混淆。 两者最本质的区别是在所用的波上,波长不通,Radar属于毫米波,通常是4-12mm; lidar用的是激光波长通常在900-1500nm之间。
Since radar wavelengths are larger, their returned results aren’t as detailed as LiDAR sensors. LiDAR has higher resolution and can provide more detailed and accurate measurements than radar. LiDAR is generally more accurate than radar because it uses laser light, which has a very short ...

Radar system solutions are specialized and can meet the demanding needs for accuracy, real-time performance, and reliability in extreme weather conditions.
Lidar and radar remote sensing systems emit different types of waves, which determines further distinctions between the two and accounts for their diverse uses.
