Some interesting video stills
GarryB you have stated earlier in this topic that the Arbalet could probably detect incoming MANPADS at distances about 5km away. Do you have sources or links to the Thread Detecting and Classifying performance of the Arbalet, would appreciate for such informations?
It was included in early advertising material for the radar system.
The Rusarm website used to have entries on Russian weapons but they have closed that part of their site down.
Here is a website: http://aerospace.boopidoo.com/philez/Su-15TM%20PICTURES%20&%20DOCS/Overscan%27s%20guide%20to%20Russian%20Military%20Avionics.htm
Scroll down to the section on the FH-01 Arbalet and scroll down through the models to find this:
Search limits, azimuth: 360°, elevation ±30°
Detection range for Attack aircraft: 15 km, Stinger missile: 5 km
Tracking limits, azimuth: ±60°, elevation: ±30°
Tracks up to 20 targets
I suspect his source was similar to where I got the info.
I think Arbalet as MMW radar could detect MANPAD from frontal direction, where radar look. But Ka-52 is equipped with with MAWS sensors for round the clock detection of incoming missiles as part of ESM suit, which than launch chaffs and flares and DIRCM against missiles. If I'm correct Ka-52 will soon also get radar jammer for protection against AMRAAM missiles.
The nose mounted MMW radar antenna only sees about 70 degrees and would not be much good for detecting a stinger attack.
It is the above rotor mounted cm wave antenna that can detect stingers at 5km, though the president-M DIRCM suite could probably detect it from similar distances or further away due to their IR signature and of course it can also use laser turrets to dazzle the IR seeker and defeat the missile, so the above rotor antenna becomes less necessary. Knowing what is in the air space around you would be useful however IMHO.
for example the Mi-28 Arbalet uses both CMW and MMW radars in once so one is for surveillance the other for FCR,ground mapping and following, so the surveillance should be able to rotate to cover 360° or it is just kind a lack of surveillance.
The radar in the Mi-28N is different and has two antennas in the one ball above the rotor... the CM wave antenna giving 360 degree coverage and offering much greater detection and tracking range than the MMW radar. The MMW radar points forward in an arc of about 70-90 degrees.
Because of the frequency the MMW radar has a range of between 12km and about 18km or so depending on the target and the weather/moisture level in the air. The cm wave radar sees much further and is less effected by moisture and weather conditions and will likely show air targets at much greater ranges... 25-30km for large aircraft, 15-20 for fighter sized aircraft and large missiles and 5-8km for small missiles.
The radar on the Ka-52 has a MMW radar in the nose and they don't seem to be fitting the above rotor mounted cm wave 360 degree radar in the aircraft they are testing... perhaps they think President-M can do the job and 360 degree radar is not needed... or is not worth the effort/cost.
