Abstract
An interferometric receiver for electromagnetic signals comprises at least two reception channels. Each channel consists of an antenna (A1), followed by a single sideband mixer (M12) and a mixer (M14). As a local signal, the mixer (M14) receives a signal similar to the received signals, taken, for example, from an auxiliary antenna (AR) followed by a limiting amplifier (ALR). The first mixer (M12) receives a frequency from a generator (GFI), which frequency is equal to the value of the intermediate frequency used in the stages (FI1) of this type following the mixer (M14). A phase processing can then be carried out and different countermeasures taken, the simplest of which is a visualization (VI).
