Which radar mode is associated with a field of regard described as Spot SAR?

Explanation:
Spotlight (Spot SAR) imaging focuses the radar on a very small ground patch, keeping that patch in the beam as the platform moves. Because the system dwells on and steers to that spot, it builds a long synthetic aperture for that area, which produces the highest azimuth resolution. The field of regard is therefore a tight spot, not a wide swath, which is exactly what “Spot SAR” describes. In contrast, Stripmap SAR covers a broader strip with moderate resolution, ISAR uses target motion to generate the aperture, and Weather Radar is not a SAR mode.
