Abstract: A method for managing track crossovers and a device for tracking mobile objects that is suitable for implementing the method are provided. The method for managing track crossovers comprises, for each track at a given time, a step Stp1 of testing in order to determine whether the track in question is ambiguous or not at the given time and, if the track is ambiguous, a step Stp2 of specific processing of the estimate of the track.

Abstract: Disclosed is a method for deinterleaving radar signals, the method including: —the reception of electromagnetic signals by a receiver (12) and the extraction of the pulses from the received signals, and —the formation of pulse trains grouping together at least three pulses spaced apart by a same pulse repetition interval, each pulse train being defined by the pulse repetition interval. The method further includes: —the grouping together of the pulse trains having a same pulse repetition interval according to a predefined grouping law in order to form pulse plateaus, and —the association of the pulse plateaus according to at least one predefined association law in order to obtain deinterleaved radar signals formed from the concatenation of the pulse trains of the associated pulse plateaus.

Abstract: This method of bonding the heads of connecting pins previously inserted in a ceramic substrate to the eyelets of conductors formed on the top surface of said substrate comprises the steps of: applying a droplet of flux to the head of each pin; applying a solder ball to the head of each pin where it is held in position because of the adhesive capacity of the flux; heating in a furnace containing a nitrogen atmosphere and having a peak temperature of 350.degree. C. to cause a solder reflow; and allowing to cool to enable the solder to set and to provide a permanent electrical and mechanical bond between the head of the pins and the eyelets. This method is suitable for use in manufacturing electronic modules employed in computers.
