ABSTRACT:
An optical miss distance detector and/or fuzing device for a missle. Four tical ring sensors are disposed around the missile body and the active sensing regions of the first and second sensors are disposed at an angle of 90.degree. to the missile axis thereby forming first and second cones of 90.degree. with respect to the axis while the active sensing regions of the third and fourth sensors are disposed at an angle of other than 90.degree. to the axis thereby forming cones of other than 90.degree. with respect to the axis. The third and fourth sensors are positioned along the axis so that the apices of the third and fourth cones coincide respectively with the apices of the first and second cones. The miss distance and relative velocity of the missile and the target are determined based on the times of interception of the cones and the azimuthal angles of interception. A fuzing arrangement is connected to the sensors which generates a detonation signal responsive to a predetermined order of interception of the cones indicating that the target is crossing the missile within a predetermined range.
