9S80 (Dog Ear) Russian Target Acquisition Radar System

The Dog Ear (with the Russian designation of 9S80) is a Russian ground-based, target-acquisition radar mounted on an MT-LB multi-purpose tracked vehicle or MT-LBu armored command and reconnaissance vehicle (ACRV). It uses an open-mesh, rounded-rectangle parabolic antenna. The radar supplies target alerting information to the SA-13 Gopher (Russian 9K35 Strela-10) surface-to-air missile (SAM) system. Deployment usually involves one system for each air defense battery/battalion. --- Additional Data (TRADOC ODIN WEG) --- Frequency: 2–4 GHz (S, NATO Band E/F) Antenna Dimensions: 2.5 x 2.5 m Associated Weapon Systems: Оса-АКМ (Osa-AKM): 9М33М3 / 9M33M3; Стрела-10 (Strela-10): 9М333 / 9M333 Role: SHORAD Command Post/3D Surveillance Remarks: Main command post for Osa/Strela-10 --- From Radartutorial.eu (https://www.radartutorial.eu/19.kartei/11.ancient9/karte029.en.html) --- The PPRU-1 “Ovod” (from: Podvizhnyy Punkt Razvedki i Upravleniya - “Mobile Reconnaissance and Command Post,” Cyrillic: ППРУ-1 «Овод», GRAU index: 9S80, NATO designation: “Dog Ear”) was an analog surveillance and target acquisition radar operating in the C-Band (IEEE designation) or G-Band (NATO designation), mounted on an MT-LB multi-purpose tracked vehicle or an MT-LBu armored command and reconnaissance vehicle (ACRV). The vehicle with the radar served as a command post for air defense missiles and anti-aircraft gun batteries. The antenna featured a parabolic reflector with a grid surface and a horn radiator. The basic version also included an integrated friend-or-foe identification device using the Kremnij-2 Standard . Developed in 1976 and entering service in 1978, the PPRU-1 was later replaced in 1992 by its successor, the PPRU-1M, which included an identification device based on the Parol . This was succeeded by the PPRU-M and -M1, which used the same antenna as depicted in Figure 1. In 2007, the PPRU-1M-2 was introduced, featuring a new digital 3D radar in the X-band.
