Like its Cousins radar and sonar, lidar (light detection and ranging), works by broadcasting electromagnetic waves towards a target and then building up a picture from the reflection.

与雷达和声纳技术相似，激光雷达(光探测和测距)的工作原理是通过向目标发射电磁波然后根据反射波构建图像。

Radar uses the reflection of microwaves of objects to determine their location.

雷达利用物体的微波的反射来确定物体的位置。

In the Madagascan data, for example, the choppiness of the waves in the open stretches of the Indian Ocean can be contrasted with the smooth reflection of the radar signal from the enclosed, calm waters of the Baie de Diego.
