In later manuals. Specifically the Joint Electronics Type Designation system manual MIL-STD-196a dated 9May57
SCR stands for Surface Water Craft, Carrier, Receiving, >passive/detection.
Pardon me, but i am not seeing how this helps. The Navy's 2 to 4 letter system and the Army's SCR system were both replaced, for new gear, by the AN system, i think 1943.
