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.

Target seeking head for a missile, comprising: a gyro rotor mounted for rotation about a spin axis, which rotor is mounted in the missile for angular movement of its spin axis with two degrees of freedom, and a target field scanning device with an optical system arranged on the gyro rotor, and a central, stationary detector, characterized in that (a) the gyro rotor (18) has a convex calotte-shaped peripheral surface (28), (b) this surface (28) is surrounded by a concave calotte-shaped bearing surface (30) substantially concentric thereto and stationary with respect to the missile, while forming a narrow air gap (32), and (c) pressurized gas conduits (34,36) open into the bearing surface (30), through which conduits pressurized gas is permitted to be introduced into the air gap (32) for centered air bearing of the gyro rotor (18), freely movable to all sides.
