en realidad puede captar un RCS de 50,000 a 400km como una fragata , en ningun documento dice que puede detectar un RCS de 3 metro cuadrado,
Alcance contra un blanco de RCS 3m2 es de 350-400km
The Zhuk-MSF / Sokol-3 from the Phazotron NIIR OKB
Zhuk-MSF is the most up to date radar design by Phazotron. Sokol uses a non-equidistant rather than the traditional linear radar field distribution, which, Phazotron says, allows a fivefold radar cost reduction over a traditionally designed phased array radar. The production radar will have a 980mm antenna diameter (37dB gain) and weigh 275kg. The radar tracks 24-30 targets, engages the most dangerous 6 to 8 of them. Its electronic beam steering will give ±70 deg spatial coverage in both axes. Power output is 8kW peak, 2 - 3kW average. It is designed for high reliability, and is frequency agile with LPI and anti ECM features. Phazotron says it will be capable of interleaving between air-to-air and air-to-ground modes.
Velocity search: 245km head-on vs fighter target.(This figure is no longer quoted. The mode may have been removed)
Range-while-search, lookup mode: 180-190km head-on / 80km tail-on vs fighter target.
Range-while-search, lookdown mode : 170km head-on / 60km tail-on vs fighter target.
Track-while-scan mode: 150km head-on vs fighter target.
Against a large target such as a bomber or AWACS aircraft detection range comfortably exceeds 300km.
“Eyes and ears”
The core of the Su-35 armament is a new radar control system with a phased antenna array (Irbis-E). It features unique capabilities in terms of the target detection range. This is a development V V Tikhomirov Research Institute of Instrument Production. In design, this is an X-waveband multi-role radar with a passive phased antenna array (PAA) mounted on a two-step hydraulic drive unit (in azimuth and roll). The antenna device scans by an electronically controlled beam in azimuth and angle of elevation in sectors not smaller than 60°. The two-step electro-hydraulic drive unit additionally turns the antenna by mechanic means to 60° in azimuth and 120° in roll. Thus, in using the electronic control and mechanical additional turn of the antenna, the maximum deflection angle of the beam grows to 120°.
Irbis-E radar control system detects and tracks up to 30 air targets, retaining continuity of space observation and engaging up to eight targets. The system detects, chooses and tracks up to four ground targets in several map-making modes with various resolution at a range of up to 400 km, without stopping to monitor the airspace.
Irbis-E radar detects air targets with an absolute cross section of 3 m2 on a head-on course at a range of up to 400 km.
Being an improvement on radars with a PAA, Irbis has much better capabilities: expanded (by more than twice) operating frequency band, increased from 70о to 120о target detection and tracking zone in azimuth, substantially (by 2-2.5 times) increased effective range, improved anti-jamming capability, etc. In this aspect, Irbis is comparable to the best foreign counterparts, outperforming most of the US- and Wes-European-made radars with passive and active PAA.
The Research Institute has been developing Irbis since 2004. By now, the engineering prototypes of the system have passed the required bench trials. The first of them has been installed on the Su-30MK2 flying laboratory and is undergoing flight tests. The first flight of the flying laboratory with Irbis onboard occurred in early 2007 at Gromov Flight Test Institute. During the flight, the laboratory proved the superior performance of the new radar in the air-to-surface operating mode.
Among other new onboard systems of the Su-35 is modern navigation and radio communication equipment, systems maintaining fighters operation in a formation and a highly efficient electronic countermeasures suite. The component package of the latter and its complementation with specific jamming devices can be determined by the customer.
Irbis-E radar detects air targets with an absolute cross section of 3 m2 on a head-on course at a range of up to 400 km.

Es un 27, Orel... Nos pongamos como nos pongamos esta es la enesima version del SU-27.

Cesar19, ICBM puso esto, (que he visto que puede venir de aquí, abril de 2006 http://www.zonamilitar.com.ar/foros/showthread.php?t=51 )Alcance contra un blanco de RCS 3m2 es de 350-400km
Y eso es una falacia como la copa de un pino.
¿Estos datos sobre el futuro radar Zhuk-Sokol del PAK FA son correctos? (como véis, nada que ver con esa fantasmada del Irbis)
