Model 9602 – Radar Synchronizer / Antenna
Controller
The Radar Synchronizer / Antenna Controller is used for
Pulse Repetition Frequency (PRF) generation and
synchronization of the radar system. It also controls the
operating parameters of the radar antenna.
The synchronizer includes a PRF generator
equipped with push buttons to select the PRF and either
single or staggered mode. Two sets of outputs are used
for synchronization, one at the selected PRF and one at
1024 times the selected PRF.
The antenna controller provides three control modes
for the radar antenna: manual mode, where speed
(clockwise or counterclockwise) is manually controlled;
PRF locked mode, which synchronizes the rotation of
the antenna to the system PRF; and SCAN/TRACK
mode for 120-degree scanning. A three-digit display that
can be switched to show antenna position or speed is
provided. The controller accepts feedback signals from
the encoder on the rotating antenna pedestal and
generates a command signal for output to the antenna
motor driver. The controller also generates azimuth
information required by other system modules.
Unregulated DC power is automatically supplied to
the Radar Synchronizer / Antenna Controller through
self-aligning connectors when it is installed on the Power
Supply / Antenna Motor Driver.
Model 9603 – Rotating-Antenna Pedestal
The Rotating-Antenna Pedestal is the mount and drive
motor for the radar antenna. It provides the RF
connection between the antenna and the radar
transmitter and receiver. Antenna position feedback is
obtained from an incremental optical shaft encoder, the
output of which may be monitored through front-panel
test points. The RF section includes a circulator for
simultaneous transmission and reception. A rotary joint
provides RF coupling to the rotating antenna mount.
Model 9604 – Radar Antenna
The Radar Antenna mounts on the rotating-antenna
pedestal and has a miniature plug-in connector for quick
RF coupling. It uses an offset-feed design to reduce
masking effects. A screen of microwave-radiation-
absorbing material is also supplied, which, although not
required due to the low level of RF power radiated by the
