TECHNICAL DESCRIPTION
Moving Target Indicator Groups AN/GPA-7 and
AN/GPZ-7A eliminate or markedly reduce returns from
Frequency: 1150 to 1400 mc
stationary targets that might otherwise obscure echoes
Operating Voltage: 120 vac, 60 cps, 1-ph
from moving targets. These groups modify Radar Set
AN/CPS-5 to provide MTI on existing indicators and to
allow antenna rotation speeds up to 10 rpm.
