GUIDANCE OF AA MEDIUM RANGE MISSILE WITH ACTIVE SELF-GUIDANCE HEAD AT GUIDANCE TO GROUP CONCENTRATED TARGET Russian patent published in 2015 - IPC F41G7/22 

FIELD: aircraft engineering.

SUBSTANCE: control over AA mid-range missile with active self-guided head at guidance to the group concentrated target is based on the application of statistic characteristics of the dependence of angular interferences of radar target on its linear sizes. It consists in that the magnitudes of the target angular coordinates are subjected to adaptive filtration by α-β-γ smoothing process and correction algorithm. The magnitudes thus obtained correspond to angular coordinates of actual target of said group target, not to apparent centre which can be located beyond the limits of the location objects geometrical sizes.

EFFECT: higher accuracy of missile guides at negative interference effects.
