PRV-11 “Side Net”
The PRV-11 „Vershina“ (Russian designation: 1RL119; Cyrillic: 1РЛ119 «Вершина»; NATO designator „Side Net“) was a radio altimeter of the former Warsaw Pact countries, developed and produced in the former Soviet Union since 1958.
The radar was housed in three cabins. The transmitting-receiving cabin with the parabolic antenna was mounted on a KZU-16 type rotating mount and was usually placed on a small mounded hill. The viewing equipment cabin on a two-axle trailer was deployed somewhat apart from it. Another cabin on a two-axle trailer housed a power supply unit and workshop accessories. Altitude determination was carried out after target assignment by a panoramic surveillance radar or by an automated guidance and control system.
