P-20 «Periskop» was operating in S-Band air surveillance radar using V-Beam for measuring the elevation angle of the aim. The radar used 5 transmitters and receiver channels, three channels on the lower antenna, and two channels on the upper antenna.
This radar was developed in the late 40s, and was used in the former Soviet Union since 1951. It was replaced by the successor P-30 and P-37.
