- А не надо ничего опровергать: цель с ЭПР=1м2, обнаружение - 105 км, захват и автосопровождение - 65 км. Никто не против.
я против.
ибо пересчет тупой и фактами не подтвержден.
ну не будем же мы считать за факты твои измышлизмы
"The N007 Zaslon was the first phased-array radar to enter service on a fighter aircraft. In 1968, Phazotron had been tasked with developing the radar for the future MiG-31. Engineers prepared two prototype units, dubbed Groza and Vikhr, both based on Sapfir-series technology. The final version was called Smerch-100, but the radar failed to meet requirements. As a result, in 1971 Phazotron was ordered to pass all the documentation to its consortium partner NIIP. The result was the Zaslon radar. The task was very difficult, since one of the main requirements was engaging cruise missiles, and the experienced Phazotron had failed to solve the problem of detecting small objects against ground clutter and tracking multiple targets simultaneously. Finally all the problems were solved, with lots of assistance from NPO Istok, who helped design the phased array, and Leninetz who were to build it, and the system finally reached service in December 1981. Zaslon is double the weight of the AWG-9, the largest US fighter radar. The NIIP team believed that the advantages a phased-array radar gave in terms of near-instantaneous scanning and multitarget engagement capability (a typical mechanically-scanned antenna can take 12-14 seconds to complete a scan) were worth the weight and cost penalties. First tests of the radar were conducted in 1973, and it was first flown on a test aircraft in 1976. On February 15, 1978, a mission in which ten targets were detected and tracked was performed for the first time. In 1981, MiG-31 aircraft carrying the Zaslon radar entered service with the Air Defense aviation, and became fully operational in 1983.
The 1.1m diameter, 30cm deep, phased array antenna weighs 300kg, the whole radar weighing in at 1000kg. Zaslon uses an Argon-15A computer (first airborne digital computer designed in USSR). Zaslon operates in 9-9.5 GHz band. It detects and engages targets down to 25m, including cruise missiles. Maximum possible search range is 300km for a large airborne target.
Range, headon, versus bomber: 180-200km search, 120-150km track
Range, tailchase, versus bomber: 90km search, 70km track
Range, headon, versus fighter [5 м2]: 120-130km search, 90km track
Zaslon can detect targets as small as 0.3 sq. m radar cross-section (RCS) to a maximum range of 65 km
Radar scan limits are ±70 azimuth, +70/-60 elevation.
Target track TWS mode, track 10 and engage 4.
Average power transmitted is 2.5kW.
MTBF is 55 hours."
