خد بالك من التوصيفات الردار ومراحل تطورة
لان المنتدي هنا كان فية ناس بتقول ان fga-29 هو هو fga-35 ودة مش صح
The aircraft's avionics system has been integrated into the fire-control and navigation system by Ramenskoye Design Bureau (RPKB). All of the devices are interconnected by a data bus compatible with MIL-STD-1553B and controlled by a computational system made by RPKB. The MiG-35's main fire-control sensor is the Zhuk-AE radar with active electronically scanned antenna (AESA) made by Phazotron- Nauchno-Issledovatelsky Institut Radiostroeniya (NIIR) Corporation in Moscow. A mock-up of the preliminary variant of this radar was showcased at the 7th International Aviation and Space Salon MAKS exhibition at Zhukovsky in August 2005. The radar had a 700 mm diameter antenna made of 1,088 transmit-receive (TR) modules (272 packs with four modules each), but at 450 kg was considered too heavy. In the next design, the weight of individual components was reduced, cut-outs in the radar body were made and a light magnesium alloy used.
To further reduce the weight to 220 kg the antenna diameter was decreased to 575 mm and the number of TR modules reduced to 680 (170 packs with four modules each). An experimental Zhuk-AE radar (the previous planned designation Zhuk-MAE was abandoned) was made with this design at the end of 2006 and then installed on the MiG-35 shown at Aero India. Zhuk-AE was due to start flight tests in March as the first Russian radar with active electronic scanning and another prototype radar enter testing at the same time.
An initial batch of 12 Zhuk-AE radars is due to be manufactured in 2008. The first stage Zhuk-AE radar (also designated FGA29) shown at Aero India is a modernised version of the mechanically scanned Zhuk-ME radar fitted with new AESA antenna. It uses the Zhuk-ME radar computing system including data processor, signal processor and software as well as the clock generator. The Zhuk-AE/FGA29 radar can be built by converting Zhuk-ME radars. Phazotron-NIIR will probably offer this manufacturing option for users of Zhuk-ME such as Algeria, Eritrea, India and Yemen.
Threat tracking
The Zhuk-AE/FGA29 is a multifunction X-band radar (3 cm wavelength), which can track and engage air, ground and sea targets. The radar in its present form has a search range of 130 km against fighter aircraft with a radar cross-section of 5 m2.-Phazotron claims that thanks to selecting proper range between radiating elements, a ± deflection of the antenna beam was achieved without parasite side lobes. The radar can track up to 30 air targets and engage six of them simultaneously.
The second stage radar, designated Zhuk-AE/FGA35, will be fitted to production MiG-35 fighter aircraft. They will receive a new computing system and new multifunction wideband generator. According to Phazotron, these changes mean AESA technology can be better exploited and new radar operation modes introduced. Additionally, due to a reduction in the size and weight of the radar modules, the antenna mirror can be moved further away from the nose of the aircraft and its diameter increased. The FGA35 will operate with a 700 mm diameter antenna with between 1,000 and 1,100 TR modules. The present design suggests there will be 1,064 modules, but slight changes are possible. The range of Zhuk-AE/FGA35 will be 200 km (for a 5 m2 target). The radar will be capable of tracking up to 60 air targets and engaging six of them.
