Abstract: The invention relates to a receiving station (1x) of a system for processing signals originating from an emitter, comprising: a first receiver (3) configured to acquire signals from the emitter; and a second receiver (4) configured to acquire signals from a satellite navigation system. The station is characterised in that the first receiver (3) and the second receiver (4) are synchronised by the same local clock (6) generating a local time base, the acquired signals being dated by said time base.

Abstract: The invention relates to a method for estimating parameters of a single signal or mixed-frequency signals in a given band. The method includes the following steps: receiving (E0) a single signal or mixture of signals y(t) in a given frequency band, determining (E3) for L, a strictly positive real number taken in a set of q, q being strictly positive, predetermined value {L1, . . . ; Lq]} of the spectral correlation function (I), where (II) is the cyclic autocorrelation function for raising the sampled version y(n) of the signal y(t) to the power of L, where Ft[.] is the Fourier transform, and where, for each q, α can separately take one or more discrete values and/or cover one or more value ranges, —processing (E4) each transform LSCFy(f, α), L being taken in a set of q, q being strictly positive, predetermined values [Li; . . . Lq] for extracting therefrom a set of peaks pi, that is, local maxima detected on the basis of the variables f and α or on the basis of the single variable f for each discrete value of α, each of said peaks being characterized by a triplet [Lapi, LFFpi, Lapi] are respectively the frequency and cyclic frequency at which said triplet is located and LApi is the amplitude thereof, and identifying (E5) groups of triplets [Lapi, LFpi, Lαpi] as being the signature left by a set of parameters making up the signals present in the given frequency band.

Abstract: The invention concerns an acquisition aid antenna device (3), intended to be secured to a main antenna device, the acquisition aid antenna device (3) comprising: —a multiband acquisition aid antenna feed (7), suitable for receiving radiation emitted by a target, and—a lens (9) arranged in the main reception lobe of the acquisition aid antenna feed (7) for concentrating the radiation received from the target towards the acquisition aid antenna feed (7). This device makes it possible to detect targets that are outside the useful beam of the main antenna device, and to use an acquisition aid antenna feed identical to the feed of the main antenna device.
