Hey heartwinlion, do you have any infos about the radars of Su 34/35 and what the differences to Mki are?
SU-34 FULLBACK
Large Leninets B-004 multimode phased array radar, passive phase shifter technology with a Travelling Wave Tube (TWT) transmitter. The radar is claimed to be highly modular with redundant components, reflecting the APQ-164 model to achieve very high mission reliability on long endurance sorties. The X-band design is claimed to achieve a 15 kW peak power rating, although production radars could see the use of higher rating TWT transmitters since developed for the NIIP BARS series.
The radar is claimed to provide a range of 200 to 250 km (108 to 135 NMI) against large surface targets, ground mapping capability to 150 km (81 NMI), Doppler beam sharpened ground mapping to 75 km (40 NMI) and GMTI target tracking to 30 km (16 NMI), the latter similar to contemporary Western attack radars like the APG-76. Detection performance against fighter sized aerial targets is claimed to be 90 km (48.6 NMI), comparable to the N-001 series. A Synthetic Aperture Radar high resolution groundmapping mode was planned, and given its existence in the evolved N-001/N-011M series, does not present difficulties. The radar provides a low altitude terrain avoidance mode, and automatic terrain following capability.
Su-35 Irbis phased array radar
The Su-35 new fire control system consists of the N035 Irbis multifunction radar system and the OLS-35 electro-optical search-and-track system. The N035 Irbis (Irbis-E for export) is an X-band radar with a 900mm passive phased array. Developed by the Tikhomirov NIIP institute the Irbis radar is a derivative of the N011M Bars radar with wider search zone, increased detection range, wider range of operating frequencies and improved resistance to jamming.
The N035's computing system consists of two Russian Solo-35 processors. A new two-stage mechanical drive mounts the phased array. The passive electronic array scans 60° in azimuth and elevation, while the mechanical steering enables the array to rotate an additional 60° for a wider search zone. The Irbis-E is capable of tracking of up to 30 aerial targets in track-while-scan mode and allows simultaneous engagement of two targets using semi-active radar homing missiles or up to eight targets using active radar homing missiles. The Irbis-E is advertised to be capable of detecting and tracking a fighter-sized target head-on at 350-400 km range using its long-range detection mode within a limited sector. It is also claimed to be capable of detecting 'super-low-observable' targets with 0.01 m2 RCS at 90 km range.
For ground attack, the radar is capable of terrain mapping and target acquisition in different resolutions using Doppler beam sharpening and synthetic aperture focusing modes. In combined ground and air mode, the radar is capable of tracking aerial threats with sufficient precision to engage with active radar homing missiles.
Future options for the Su-35 might include a rear-facing radar such as the N012 to be fitted in the tailboom, but the current Su-35 does not contain such equipment.
