ships. It is also used as a back-up radar on large
combatants. It provides a true bearing display for
coastal piloting and a capability for radar navigation and
station keeping.

General Theory of Operation
The AN/SPS-64(V)9 has a minimum detection
range of 20 yards on a radar cross-sectional target of 10
square meters, 3 feet above the surface of the water. It
can operate in either true or relative bearing when used
with Navy gyrocompasses.
Some special operating features of the radar
include:
Ship line voltage protection
Ship Heading Marker (SHM)
Variable range marker
Configuration
Figure 2-3 provides a general overview of how this
radar operates.
Unlike the AN/SPS-67 radars, this
off-the-shelf radar system was not designed to use
existing antennas and indicators. All the components,
including the indicator and the antenna system, are
unique to the AN/SPS-64(V)9.
SIGNIFICANT INTERFACES.— Information
from the AN/SPS-64(V)9 interfaces with the following
Navy equipment:
Blanker/Video Mixer Group, AN/SLA-10
Indicator Group, AN/SPA-25( ) or equivalent
Synchro Signal Amplifier, Mk 27 or equivalent
Mk 19 gyrocompass or equivalent
FOR THE MAINTAINER.— The AN/SPS-
64(V)9 is designed and constructed according to the best
