RADAR Simulation SAR
• Radar Designers developed methods to synthetically create
a large antenna by taking advantage of the forward motion
of the ownship, and thus was born Synthetic Aperture Radar
(SAR)
• SAR processing requires phase corrections for every
pulse the radar receives. Doppler filtering is used to
provide corrections
> The use of Doppler filtering precludes scanning
directly along the ownship’s flight path

RADAR Simulation Spot & Strip SAR
The advent of SAR processing gave rise to several applications.
Spotlight mode (Spot-SAR)
• The radar beam is continuously trained on a target area while the
ownship continues along its flight path. This mode allows the radar
operator to maintain surveillance over a designated area for long
periods of time, and can also be used to produce detailed maps. It
can also be used for target identification.
Strip SAR
• Similar to a Spot-SAR for which the position is updated with the
ownship motion

RADAR Simulation ISAR
Inverse SAR (ISAR)
> ISAR is used in maritime environment for target
identification, when the sea state doesn’t allow
the use of Spot-SAR. When the sea state is at
value 2 or higher, the target has a rotational
motion with respect to the ownship.

RADAR Databases
• Radar is a CDB native application
• CDB is an open format, allowing
the user to create databases
through:
> Creator and TerraVista Toolset
> Any CDB compliant third party
toolset
