WebApr 3, 2024 · According to the official website Irbis E can detect a fighter with RCS of 3m2 at 350 Km. We can use these figures to calculate its detection range against F22. F22 RCS is 0.0001m2. Det range = 350 Km / (4th root of 3/ 4th root of 0.0001) = 27Km So irbis E can detect a fighter aircraft with 0.0001 m2 RCS at 27 km approximately. WebAug 22, 2009 · If one assumes that the average time until detection is half the total volume search time, the plane with the described radar will usually detect the other plane 25 seconds after that other plane gets close enough for its RCS to give it away. 1600 kmh is 444.4 meters/second - so that means planes will be 11 kilometers closer to each other at …
