AN/SPS-6, -6A, -6B, -6C
Peak Power Output: 750 kw
FUNCTIONAL DESCRIPTION
Pulse Repetition Rate: 150 to 600 pps
Pulse Width: 4 sec at 150 pps;
Radar Sets AN/SPS-6, -6A, -6B, and -6C are
shipboard, air and surface, search radar equipments that
1 sec at 600 pps
supply target bearing and range data to PPI and A-
IF. Frequency: 30 mc
scope indicators. These radars provide sweep trigger,
Operating Voltages and Power Requirements:
video voltage, and bearing data for as many as four
115, 198, 210, 220, 396, 420, or 440v, 60 cps,
external PPI indicators of the VE, VJ, and VK or similar
1-ph, 5.5 kva
types. They are designed for either local or remote
Antenna Type: Unidirectional, parabolic type
operation, and a dual feedhorn radiator on the antenna
reflector
propagates and receives both radar and IFF signals.
Horizontal Beam Width: 3.5 deg
These radar sets are essentially similar, the major
Vertical Beam Width:
difference being the antenna used with each model.
AN/SPS-6 - 10 deg
