Abstract
A method () for detecting broadcast signals, transmitted by terrestrial sources () and received by a satellite (), in individual signals obtained respectively from different individual antennas () of an antenna array () of the satellite, includes a first detection iteration () and a second detection iteration (), each of the first and second detection iterations including a step () of forming, from the individual signals, virtual beams of different respective main radiation directions, and a step of searching for the presence of broadcast signals in the virtual beams. Furthermore, for at least one broadcast signal detected during the first detection iteration, the respective contributions of the at least one detected broadcast signal to the different individual signals are attenuated, relative to the first detection iteration, for all or part of the virtual beams formed during the second detection iteration. A system () for detecting broadcast signals is also described.
