Phased Array Antenna Controller
581968 (9613-00)
The Phased Array Antenna Controller is used for beam steering
control of the Phased Array Antenna (PAA), Model 9612. It allows
the PAA to be operated in the following three different scan
modes: manual, continuous, and PRF locked (radar PRF
dependent). The beam sequence (i.e., the order in which the
beams are scanned) can be either linear or pseudo-random, or
consists of even-numbered beams only (skips over every second
beam). A 3-digit display on the front panel of the Phased Array Antenna Controller indicates the number of the
selected beam, the angular position of the beam or the scan speed.

SAR Controller
581970 (9614-00)
The SAR Controller allows motion control of the small-aperture
horn antenna installed on the moveable carriage of the Target
Positioning System (Model 9607-1) when the Basic Radar
Training System (Model 8096-1) is used as a synthetic aperture
radar. Antenna motion commands are received from the SAR
Processor (RCS/ISAR Processor, Model 9611 equipped with the
LVSAR software) via a USB port connection. The SAR controller
also ensures that the radar echo signal acquisition is properly
synchronized with the horn antenna motion. The SAR Controller
is provided with an LED indicator that lights up when faulty
operating conditions are detected in the Target Positioning
System. A reset button on the SAR Controller allows normal
operating conditions to be restored.

Synthetic Aperture Radar Software
The Synthetic Aperture Software is a Windows
®
-based application that implements a powerful SAR processing
unit that produces SAR images from the target echo signals acquired during a scan of the small-aperture horn
antenna over the complete aperture length. The Software is also an intuitive user interface that provides all the
controls and settings required to operate the Synthetic Aperture Radar as well as to display fine SAR images.
