The model of dynamics and control of modified optical scanning seeker in anti-aircraft rocket missile

•The structure of the modified optical scanning seeker was presented.•The model of dynamics and control of modified optical scanning seeker was developed.•Preliminary research of dynamics of controlled scanning seeker was carried out.•The seeker maintains accurately the set direction in space despite the occurrence of large external interferences.

The paper presents the concept of a modified optical scanning seeker. Programmed and tracking controls have been developed with the simultaneous influence of external interferences from the direction of self-guiding rocket missile. The numerical analysis for the proposed scanning seeker has been conducted. It appears from the conducted research that the seeker maintains accurately the set direction in space despite the occurrence of large angular accelerations of the missile. Moreover, the control of the seeker's axis is done with sufficient accuracy for self-guidance with the use of small control moments.
