Abstract: The method processes measured vertical profiles of the power of the echoes returned following a transmission of radar signals, each measured vertical profile being a function of the sweep angle of the radar beam and associated with a given pointing angle/distance box pair of the radar beam. The method generates a synthetic vertical profile of the power of the echoes returned by the ground only, and includes, for each measured vertical profile: superposition of the synthetic vertical profile on the measured vertical profile in question, for various values of the sweep angle, calculation of the error that exists between the measured vertical profile and the synthetic vertical profile, for each sweep angle value in question, and an exclusion, from the measured vertical profile, of the values for which the calculated error is less than a given threshold, in order to generate a resultant vertical profile with no ground echoes.

Abstract: An optical connection device includes at least one first rigid element fitted with an end which is preferably pointed; and at least one second element comprising a part made of elastic material such as silicon. Fasteners hold the end of the said first element against the elastic material of the said second element.

Abstract: This device has, on one and the same component: an image zone having a first array of at least one line of cells integrating an electrical charge than can then be transferred from point to point in the array, along the line, up to an end of this line; a memory zone having a second array with a same number of lines of cells and a transfer zone. The line of the second array is a looped line sequenced like the corresponding line of the first array, and at the same rate, and the transfer zone includes charge divider means receiving, at input, said charge transferred from point to point in the first array along the line and dividing said charge into two sub-charges with a pre-determined relative ratio; means to neutralize the first of these sub-charges; and means to add the second of these sub-charges to the charge received at output of the looped line and to reinject the resultant total charge into the input of the looped line so as to make it recirculate therein.

Abstract: In the disclosed optic signals processor, a term-by-term subtraction is made of the N homologous values of two series of values resulting from the integration of a light energy that selectively strikes respective photoactive pixels of a charge-coupled device.
