SCR-627
SCR-627 was a medium-range stationary early warning radar operating in the VHF-Band
The antenna had dimensions of 10 × 10 m and was erected on a reinforced concrete foundation. It consisted of two superimposed antenna arrays, each with four rows of 6 dipoles in front of a common grid reflector. The phase difference of the echo signals from both antenna arrays was used to measure an elevation angle.
The radar used two PPI scopes and a special HR-scope (height-range scope) for display. For power supply, two gasoline generator sets (one spare) of 25 kVA each were used.
