ABSTRACT:
The invention relates to a feed device for a multisource semiactive antenna with multiple beams, including:
a) a nonorthogonal beam shaper device (65) splitting Nb beam input signals and combining them to form Na output signals,
b) Na amplifier modules (64),
c) an orthogonal output power splitter (63) arranged between the Na amplifier modules (64) and Ne radiating elements (61).
According to the invention, Nb.ltoreq.Na.ltoreq.Ne, and the orthogonal transfer function of the splitter (63) permits change between, on the one hand, Nb distributions at the input of the splitter (63), in which the amplitude of the Na signals is equal for each of the Nb beams, and in which the phase satisfied the condition of equality of the scalar products, taken in pairs, of the Nb excitation vectors at the input of the splitter (63), and of the scalar products, taken in pairs, of the Nb corresponding output excitation vectors and, on the other hand, Nb predetermined output distributions.
