How Radars Tell Targets Apart (and When They Can’t) | Radar Resolution

Описание: How do radars tell targets apart when they’re close together - in range, angle, or speed?

In this video, we break down the three core types of radar resolution, how each one works, and why improving one often means making trade-offs with the others.
