ABSTRACT:
A target seeking head mounted in the dome of a missile comprises a gyro rotor including a mid-portion forming a convex calotte-shaped peripheral surface. The convex calotte-shaped peripheral surface is surrounded substantially concentrically by a concave calotte-shaped bearing surface stationary with respect to the missile. A small gap is formed between the two surfaces and pressurized gas is introduced into the gap to form a gas bearing centering the gyro in the center of curvature of the convex calotte-shaped peripheral surface thereof. A target seeking scanning device comprises an annular parabolic mirror formed at the mid-portion of the gyro and a plane mirror imaging a field of view located in infinity in the plane of a detector mounted stationary with respect to the missile.
