Abstract (en)

[origin: US5669579A] A method for determining the rates of turn of the missile/target line of sight with a seeker head rigidly mounted on the missile, characterized in that the azimuth and elevation deviation angles ( psi sm and THETA sm) of the target measured with the rigidly mounted seeker head (2) in the missile-fixed coordinate system (s1, S2, s3) are transformed to the azimuth and elevation deviation angles ( psi v and THETA v) of the target based on the coordinate system (v1, v2, v3) of a virtual, gimbal mounted and gyrostabilized seeker head (2v) that tracks the missile/target line of sight (SL) by rotation with the rates of turn (pv, qv, rv) about its three axes (v1, v2, v3).
