Claim 7:
8. A system for radar-scanning a ground-surface field of view, the system comprising:
a signal generator that generates electromagnetic signals;
a plurality of antennas radially distributed about a nose-cone of a missile, each of the plurality of antennas electrically connected to the signal generator so as to receive an electromagnetic signal that causes the antenna to direct an electromagnetic beam along a principal direction characterized by a roll orientation θ to which the antenna is rotated by the missile and an azimuthal beam angle ϕ with respect to a roll axis of the missile, the azimuthal beam angles of the plurality of antennas being different from one another, each of the plurality of antennas sensing a reflected portion of the electromagnetic beam reflected from objects within the ground-surface field of view upon to which the electromagnetic beam has been directed,
wherein as the missile rotates about the roll axis the principal directions sweep conical figures about the roll axis, at least a portion of the conical figures intersecting the ground-surface field of view; and
an image processor that determines, 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 ground-surface field of view.
