P-10 “Knife Rest B”
The P-10 radar (Russian designator: “Volga A”; Cyrillic: «Волга А»; NATO designation: “Knife Rest B”) is a further development of the P-8 radar and was included in the armament of the Soviet Army from 1953. The half-width of the 2x2 antenna array was between 20 and 24° (frequency-dependent). The elevation angle was determined with a goniometer from which the target elevation could be determined with a nomogram. Accuracy of the angle determination succeeded up to ±2.5°. The radar was already equipped with a jamming protection system. The receiver sensitivity was nominally 3 µV (≙ −103 dBm), at the limits of the frequency range of 4 µV. Radar information was displayed on a PPI and a Range-Height Indicator (E-scope). In 1956 the P-10 was replaced by the P-12 radar.
