What absorbs a significant amount of RADAR energy?

Leaves absorb a significant amount of RADAR energy due to their complex structure and moisture content. When RADAR waves encounter leaves, they can be absorbed and scattered, which diminishes the strength of the reflected signals. This is particularly relevant in understanding how different surfaces interact with RADAR technology, especially in environments rich with vegetation. The absorption characteristics of leaves can affect the accuracy of distance measurements and detection capabilities within RADAR systems.

In contrast, materials like glass, brick, and snow interact differently with RADAR waves. Glass tends to reflect RADAR waves, while brick can also reflect due to its density and solid construction. Snow can have mixed effects depending on its density and structure; however, it generally doesn't absorb as much energy as leaves do in a typical context. Understanding these properties is crucial for operators when interpreting RADAR data in varied environments.
