Claim 14:
15. A method for radar-scanning a field of view, the method comprising:
generating, via a signal generator, electromagnetic signals;
receiving, via a plurality of antennas radially distributed about a nose-cone of a projectile or missile, the electromagnetic signals generated by the signal generator;
rotating the nose-cone of the projectile or missile about a rotational axis;
directing, via each of the plurality of antennas, an electromagnetic beam along a principal direction characterized by a rotational position θ to which the antenna is rotated by the nose-cone of the projectile or missile and an azimuthal beam angle ϕ with respect to a rotational axis of the nose-cone of the projectile or missile, the azimuthal beam angles of the plurality of antennas being different from one another,
wherein as the nose-cone of the projectile or missile rotates about the rotational axis the principal directions sweep conical figures about the rotational axis, at least a portion of the conical figures intersecting the field of view;

sensing, via each of the plurality of antennas, a reflected portion of the electromagnetic beam reflected from objects within the field of view upon to which the electromagnetic beam has been directed; and
determining, via an image processor and based on the reflected portions of the electromagnetic beams sensed by the plurality of antennas, directions and/or ranges to and/or velocities of the objects within the field of view.
