O-Strand Radar Practice Test

This is about azimuth (bearing) resolution. When two radar targets sit at the same distance from the radar but at different angles, you need angular discrimination to tell them apart. Azimuth resolution measures how finely you can distinguish targets by their bearing. It depends mainly on the antenna’s beamwidth and the processing technique: a narrower beam or a longer synthetic aperture gives better bearing separation, letting you resolve targets that are close in angle. Temporal resolution, by contrast, is about how often the radar updates or samples, not how well you separate targets by direction. Range resolution would handle targets separated in distance along the range axis, and Doppler resolution deals with velocity. So the scenario described points to azimuth/bearing resolution.
