Date Apr. 14, 1983.An aerodynamic body (M) provided with means for steering in response to a body control variable signal has a homing device (1) supplying a measurement signal ( epsilon m) of the error angle of the body. For intercepting a target (T) a computing unit (10), operating on the basis of relationships describing the aerodynamic behavior of the body with respect to the target, determines signal values ( sigma , theta ) representing approximations of the line of sight angular rate ( sigma ) and the attitude angular rate ( theta ). The input signal to the computing unit (10) is the body control variable signal (u, um) which is dependent on the determined approximation ( sigma ) of the line of sight angular rate. From said two signal values ( sigma , theta ) a signal value ( epsilon ) representing an approximation of the error angle is determined. An error angle difference signal value ( DELTA epsilon = epsilon m- epsilon ) is determined and fed back to the computing unit (10) for correcting quantities of the relationships thereof. |
