Guide: Barrows

A barrow is a mound of earth and/or stones raised over a grave or group of graves. Used from the Neolithic through to the Iron Age (roughly 4000 BCE to 500 CE), barrows were often constructed to honour elite individuals, such as tribal leaders, warriors, or chieftains. They are frequently found singly or in cemeteries known as barrow fields.

Synthetic-aperture radar (SAR) already relies on Doppler shifts: echoes from scatterers in a side-looking radar beam have slightly different frequencies as the platform flies past, and focusing those micro-shifts yields a two-dimensional image.
