Synthetic aperture radar (SAR) techniques rely on motion of the
radar system relative to the target. For SAR, the motion
is assumed to be produced by a moving radar system
against a stationary target. A stationary radar system can also
make use of SAR techniques provided the target is moving
in relation to the radar. This variation is known as
ISAR . ISAR is popularly employed against ships bobbing in three dimensions
on the ocean’s surface or against aircraft as they fly
across the sky.
