ABSTRACT:
A method is provided for guiding an in-flight vehicle having course divert apability toward an intercept with a target. Using a sensing device mounted on the vehicle, target data is acquired to establish a relative position vector between the vehicle and the target. A trajectory course for the vehicle is selected such that it is offset from a collision course with the target. The offset is defined within in a target impact plane perpendicular to the relative position vector. The total thrust of the vehicle associated with its course divert capability is directionally controlled through first and second orthogonal components. To reduce offset the second component is directed to cause the trajectory of the vehicle to spiral around the relative position vector.
