<p>An interferometric measurement device with a superheterodyne receiver, comprising at least two superheterodyne reception channels (R1 ... Rn) followed by respective filters (F1 ... Fn) defining the intermediate frequency reception band, and by at least one spatial sampling line (SSL) (L1 ... Ln) used in undersampling and in a differential circuit, as well as an interferometric measurement circuit (12).</p> |
