1.7 RADAR SET AN/SPS-64(V)2

Table 1-4 Radar Set

The Dual (Partial) System uses one 12-inch

AN/SPS-64(V)1, (V)2, (V)3

indicator, one 16-inch indicator, one antenna pedestal,

Recommended Spares

and two receiver transmitters, essentially the same as

the primary radar components described in paragraph

1.6. One six-position switching unit SA-2156 is used to

1.7.3 Block Diagram Description (V2)

Figure 1-5 is a block diagram showing the major

components of Radar Set AN/SPS-64(V)2.

These

components are functionally identical to those described

amplifier. This redundancy enhances system reliability

and availability. Depending on the mode of operation,
