A method for homing a projectile onto a target wherein the projectile is self-steering in an extended trajectory in its flying end phase, in particular an artillery projectile, from which there is effected a search and homing onto a target. Also provided is an arrangement for the change of a projectile which is self-steering and program-controlled during its flight end phase and which is equipped with a target searching device, in particular an artillery projectile, which is equipped with control and steering arrangements and with control rudders for transition from a ballistic firing trajectory into an extended forward trajectory and then for homing into a target approach trajectory. An arrangement is also included for the input of the characteristics of a ballistic launch trajectory into the memory of a navigational computer on board of a projectile which is self-steering along an extended flight end phase.

In a method for homing a projectile onto a target wherein said projectile is self-steering in its end flying phase along an extended trajectory, such as an artillery projectile, from which there is effected a target searching and target homing sequence; the improvement comprising: initially maintaining the extended trajectory subsequent to detecting the target object which is to be homed on; thereafter effecting a pitch angle control for transition from the extended trajectory into a steeper target approach trajectory at a further shortening of the distance towards the target object; determining the theroretical impact point on board the projectile from given firing data and from pregiven conditions during transition from an initial ballistic trajectory into said extended trajectory; and calculating on board said projectile, for said steeper target approach path towards the target object, the delay time period for transiently maintaining the extended trajectory up to the time point of leaving said extended trajectory into the target approach path at a steeper pitch angle.
