The set operated on four frequencies between 2,700 and 2,800 MHz.


The set had a search mode with a range of 40-50 miles and could switch to automatic tracking mode when the target reached within 18 miles. When in the tracking mode target data could be fed to position a nearby anti-aircraft gun battery.
The set was self-contained, built on a K-78 trailer and meant for forward area deployment. Its gross weight was 10 short tons. The overall length was 19.5 feet, width was 8 feet, height 10 feet, 4 inches. A towed trailer contained a generator power source. Thirteen men could install the set and obtain approximate data in 2 hrs. Accurate orientation and alignment took 4 additional hours.
The SCR-584 was first used in combat at Anzio in February 1944, where it played a key role in breaking up german air attacks on the confined beachhead. Employed in England against the German V1 flying bombs it achieved remarkable success.

When in the tracking mode target data could be fed to position a nearby anti-aircraft gun battery.
