| 摘要 |
The invention relates to a digital receiver which includes at least two receiving channels (1, 2, 3, 4), the method producing a digital intercorrelation (75, 76, 77) of the signals obtained at the output of at least two filters (71, 72, 73, 74) with different centre frequencies and ranks, the rank and the centre frequency of the filters being selected in accordance with a predetermined frequency-searching scope. For a given searching scope, the various sampling frequencies of the receiving channels are selected such that the ambiguous frequencies that are the result of spectral folding vary as a monotonic function of the true frequency of the signals. |
