The Radar Equations

Course Description

The weather radar equations quantitatively describe the process by which an electromagnetic pulse departs a radar antenna, interacts with scatterers in the atmosphere, and then returns to the radar. In this lesson, we derive the radar equations step by step, demystifying each term. Learners will gain a complete understanding of both versions of the radar equation – one version for a single target, and another version for distributed targets – and be able to describe how changes to each variable impact the amount of power the radar receives. These equations inform both the design and use of weather radars and their data.
