How a radar works
WebRADAR stands for Radio Detection and Ranging System. It is basically an electromagnetic system used to detect the location and distance of an object from the point where the … WebRadar measurement works according to a well-known physical principle: the reflection of electromagnetic waves by certain objects, the targets (in this case, the hydrometeors of precipitation). In the case of weather radar, the radar measures the power that is backscattered by a set of raindrops, and in this way, it can determine exactly where the …
