Abstract
The present invention relates to a conical scanning process in a radar antenna. The antenna comprises a principal parabolic reflector (1) and a primary rear-feed source (2) fed by a circular waveguide (3) and displaced with respect to the focus of the parabolic reflector (1). The conical scanning is produced by the rotary movement of the parabolic reflector (1) about the source (2), the said source (2) and the circular guide (3) remaining fixed. The present invention is applicable to tracking radars operating in the millimeter waveband.
