ABSTRACT:
A radar antenna of small overall dimensions is provided, placed in a belly radome, including a reflector of paraboloid shape of revolution about the longitudinal axis and integral with a case. This assembly is mounted for pivoting about the transverse axis and about the vertical axis inside the radome.
Rotation about the longitudinal axis called roll axis is provided by rotating the transmission source by rotation means placed inside the case and the duct. With the reflector fixed in the roll direction, the area thereof may extend over the whole of the inner section of the radome, rotation of the radar beam along the roll axis being obtained through rotation of the source with respect to the reflector.
