We understand this well. Missile guidance is interrupted when the radar reaches the roll limit of 120 degrees.
It is not stabilized In close combat. But in BVR combat mode, the radar is stabilized and operates in vertical polarization mode.
The combat use methodology states that after missile launch, the flight must be carried out without allowing the target mark to go beyond the limits of stable auto tracking. When the lock is reset, target illumination for launched missiles does not resume.
I hope you understand that the "Kadushka" maneuver goes beyond the scope of stable auto tracking.
