Bars radar Bars radar The Bars (Leopard) is a family of Russian (former USSR) all-weather multimode airborne radars developed by the Tikhomirov Scientific Research Institute of Instrument Design for multi-role combat aircraft such as the Su-27 and the MiG-29. The first Bars series radar was the N011, which was originally an X band Pulse-Doppler radar developed for the Su-27. In this original N011 form, it deployed a mechanically scanned planar array with 960 mm diameter, ±85 degrees scan sector. The peak output power reached 8 kW with an average of 2 kW. The N011 features a low noise UHF input amplifier, and
