Part of the equipment
The A-100 as a whole repeats the appearance of the A-50 AWACS aircraft, which has a radar installed in the rotating fairing over the fuselage. The radar operates in the S-band (wavelength 7.5-15 cm), has an electronic scanning in height and mechanical - along the horizon. The radar makes 12 revolutions per minute, that is, twice as fast as the A-50 Shmel radar. The efficiency of detection of flying targets is also improved. All other systems are also new, among them the navigation and flight control system PNK-PM.
On the fuselage A-100 installed additional antennas, especially noticeable round fairing in the nose, which is supposedly located antenna passive accompaniment. A similar antenna is also available at the rear of the fuselage. Another antenna is located on the side of the fuselage in the area of the fairing of the chassis. Presumably, this is an element of the airborne complex of defense. Like the A-50, the A-100 has a satellite communication antenna in the upper part of the fuselage.
The characteristics of the A-100 can be estimated from its export version A-100E. Its radar is capable of escorting up to 300 targets at a distance of 650 km (for example, a heavy bomber at a high altitude) or 215 km (an EPR target of the order of 1 km.) And control 30 fighters. The aircraft can be in the air up to six hours at a distance of 1000 km from its base. A-100 should replace the existing ARL-50 and A-50U aircraft. Russia has 17 A-50 aircraft based in Ivanovo, 250 km from Moscow.
A-50 and A-50U
By 2017, four A-50s were upgraded to version A-50U with the installation of the Shmel-M system. In comparison with the original version, "Shmel-M" is equipped with a new digital data processing system, which replaced the analog system of the previous modification. This reduced mass and increased reliability. According to some sources, the modernized aircraft can detect up to 150 targets at distances up to 600 km, compared to 45 targets for the A-50. The "Bumblebee" radar with mechanical scanning remained unchanged. The transfer of data was improved by installing LCD monitors instead of cathode ray tubes. Communication and navigation facilities have also been replaced. Unlike the base A-50, the A-50U is equipped with not only a kitchen and restrooms, but also a rest room for the crew. The old D-30KP-2 engines remained on the plane. The only external difference between the two modifications is the small planes in the fairing area of the main landing gear rails. At A-50 they served to protect the radar from reflected signals from the Earth.
Oh so the A-100 Radar only scans in elevation. Similar as the E-3 Sentry. I wonder why they not adopt full 3D scanning. Thus allow optimized sector scan mode like E-2D Hawkeye.
Russian MoD said, that A-100 is gonna be superior to NATO AWACS,actually Sentry already has a detection range of 650km something, so I suppose A-100 will have detection range of around 700-750km.
