FUNCTIONAL DESCRIPTION
Radar Repeater Equipment VK, VK-2, VK-3 VK-3a,
VK-4, VK-4a, and VK-5 function as standard PPI
repeaters, off-centered PPI repeaters, or as expanded
off-centered PPI repeaters. They may also serve as
plotting centers. These equipments can display target
data obtained from an AEW system, information from a
dead reckoning analyzer, or target data from a shipboard
radar. Service as a radar relay or target designation
transmitter, relaying target bearing and range to remote
stations, can also be performed.
The VK series equipments are similar, differing
slightly in electrical performance.
RELATION TO SIMILAR EQUIPMENT
None.
