Interferometric hyperfrequency radiometry system with mechanical scanning

摘要

The invention concerns an interferometric hyperfrequency radiometry system comprising an antenna being subject to a rotation movement around the vertical direction, with a boresight axis forming an angle with a nadir direction so as to obtain a conical scanning. The antenna is a planar array antenna, of an interferometric type with distributed elements, such that the instantaneous field of vision consists of pixels, along at least one axis perpendicular to the conical scanning for an unidimensional interferometric antenna, and along two axes for a bidimensional interferometric antenna. The elements of the interferometric antenna furthermore are connected into sub-arrays.
