Simplified homing system for a missile of the shell or rocket type

Simplified homing system for a missile of the shell or rocket type which is not actively stabilized against rolling, comprising means for detecting a target, which means are directly mounted on and associated with the missile;

• an accelerometric device mounted directly on the missile structure and including at least one accelerometer having a sensing axis radial with respect to the missile axis to detect the lateral acceleration of the missile;
• means for elaborating a guiding force F.sub.p applied to the missile via actuators acting on rudders, said elaborating means including passive means for ensuring the keeping up of the rolling movement of the missile;
• means associated with the accelerometric device for discriminating the lateral acceleration .gamma..sub.ext of the missile due to outside forces and the centrifugal acceleration .gamma..sub.c due to the rolling;
• means for determining the serviceable values related to the vector V indicating the relative speed of the missile with respect to the air in a reference system related to the missile from information supplied by the accelerometric device and the associated discriminator means;
• and means for determining serviceable values related to the vector u.sub.c representing the direction of the target with respect to the axis of the missile from target detection means, wherein the means for elaborating a guiding force F.sub.p elaborates said force from the said predetermined serviceable values related to the vectors V and u.sub.c.
