The major units of the AN/SPS-67(V)1 and (V)3
radar sets are shown in figure 2-1 and figure 2-2
respectively. As you can see, there is only a slight
difference between the AN/SPS-67(V)1 and the
AWSPS-67(V)3 versions. Think back to the basic
block diagram of a pulse radar in chapter 1 (fig. 1-4).
Relate the function blocks in figure 1-4 to the basic units
shown in figure 2-1. If you understand the basics, youll
find that no matter how many special operating
functions a radar has, the basic system is still the same.
The receiver-transmitter and video processor
components of the AWSPS-67(V) bolt to the same
bulkhead foundations used for the AN/SPS-10 series
components. The remaining components mount in the
same area of the units they replace, although they may
or may not have the same shape as the AN/SPS-10
components. The dummy load mounts on the output of
the receiver-transmitter unit.
SIGNIFICANT INTERFACES. Although
radar systems provide valuable information by
themselves, the interface of that information with other
warfare systems is critical.
The AN/SPS-67(V)1 meets interface requirements
of the following equipment:
Electronic Synchronizer, AN/SPA-42 or
Blanker-Video Mixer Group, AN/SLA-10( )
Indicator Group, AN/SPA-25( ) or equivalent
Synchro Signal Amplifier, Mk 31 Mod 8A or
The AN/SPS-67(V)3 meets interface requirements
for the following additional equipment:
Shipboard Emission Monitor-Control Set,
Data Multiplex System, AN/USQ-82(V)
Processor Converter Group,
Command and Decision System, Mk-2
Gyro Digital Converter, P/O Mk-38/39 and
Surveillance and Control System, AN/SPY-1
FOR THE MAINTAINER. The AF/SPS-67(V) is
a solid-state replacement for the AN/SPS-10 radar system.
Miniature and micro-miniature technologies are used
throughout the radar set. It is more reliable and has better
logistical support, with 92 percent of its construction being
Standard Electronic Modules (SEM).
The Built-in-Test (BIT) microprocessor sub-assembly
uses on-line performance sensors to decrease the chance
of operating the radar with an undetected fault. Using BIT
circuitry during normal operation will not degrade system
performance, nor will faulty BIT circuitry affect system
performance. When system failures do occur, you can use
BIT to isolate 95 percent of the possible faults to a
maximum of four modules within the receiver-transmitter
or video processor.
BIT circuitry uses light-emitting diodes (index
indicators) at certain test points to indicate the locations
of faults. The condition of the system at each test point
is displayed on readout indicators as GO, MARGINAL,
or NO-GO. In addition, the BIT subsystem provides an
interactive test mode that permits you to monitor certain
test points while making level or timing event
adjustments. Power and voltage standing wave ratio
(vswr) are monitored on an on-line basis. The BIT
subsystem also automatically tests itself periodically by
going into a self-check mode.
The AN/SPS-67(V) radar set operates continuously
during the ships deployment. The responsibility for the
organizational level maintenance falls on the ships
Electronics Technicians, (NEC ET-1507.)
Organizational level maintenance consists of
preventive maintenance (PM) and corrective
maintenance (CM). PM is performed according to
maintenance requirement cards (MRCs) developed for
the AN/SPS-67(V) system. PM at this level includes
checks of operational status and filter/equipment
cleaning. CM is performed according to the
AN/SPS-67(V) technical manual procedures, and
includes removing and replacing chassis-mounted piece
parts, modules, assemblies, and sub-assemblies.
Repairable modules, assemblies, and
sub-assemblies are returned to the depot according to
Navy supply procedures.
The AN/SPS-64(V)9 radar is a two-dimensional
(2D) navigation/surface search radar used as a primary
radar on small combatants and various non-combatant
