The P-12 "Yenisei" (also referred to by the NATO reporting name "Spoon Rest A" in the west) was an early VHF radar developed and operated by the former Soviet Union.

Finally Yenisei had greater accuracy with improved detection range (250 km) and better protection against passive and active interference.

[1] In addition to frequency agility the P-12 was the first Russian radar system to use the coherent cancellation moving target indicator (MTI) method to eliminate ground clutter.

[2] The P-12 "Spoon Rest A" was mounted on two Zil trucks,[2] though later with the P-12NP "Spoon Rest B" the radar antenna mast was mounted on a separate trailer cabin to allow for location away from the other components of the radar site, the P-12NA returned to a track based platform.

One particularly notable incident took place during the War of Attrition in 1969 when Israeli commandos captured a P-12 radar station from Egypt in Operation Rooster 53.
