Abstract: This antenna system has a plurality of elementary antennas configured into an array, wherein there is a reception (or transmission) channel associated with each antenna or sub-array of antennas, said reception channel having, in series: an active reception module, delay means capable of selectively introducing a pure delay of propagation of the signal picked up by the elementary antenna so as to produce a gradation of delays for the different respective elementary antennas, said gradation of delays enabling the definition of a desired pointing in the direction of the wave to be received with respect to the orientation proper to the array; and an analog/digital converter receiving, at input, the analog signal received, to deliver, at output, a corresponding digitized signal to a beam forming computer. The delay means are digital means, positioned at output of the analog/digital converter and typically comprise a digitally programmable delay generator comprising a programming input that receives a digital control word, defining the delay to be produced, from a pointing computer, a triggering input that receives pulses digitally representing the signal to be delayed and a signal output deliverying the delayed signal pulses.

Abstract: 13 L'invention se rapporte à un dispositif de limitation de signaux d'entrée d'un convertisseur analogique-numérique. Le dispositif comprend en entrée (E) un convertisseur analogique-numérique auxiliaire (2) dont la sortie est reliée à l'entrée d'un convertisseur numérique-analogique (3). La sortie de ce dernier est reliée à l'entrée négative d'un circuit soustracteur (4). Un circuit à retard (5) est câblé entre l'entrée du convertisseur analogiquenumérique auxiliaire (2) et l'entrée négative du circuit soustracteur (4). La sortie de ce dernier constitue la sortie du dispositif. Application: limitation de la tension d'entrée de convertisseurs analogique-numériques dans des chaînes de réception d'un radar. Figure 3.

Abstract: 19 This antenna system has a plurality of elementary antennas configured into an array, wherein there is a reception (or transmission) channel associated with each antenna or sub-array of antennas, said reception channel having, in series: - an active reception module, - delay means capable of selectively introducing a pure delay of propagation of the signal picked up by the elementary antenna so as to produce a gradation of delays for the different respective elementary antennas, said gradation of delays enabling the definition of a desired pointing in the direction of the wave to be received with respect to the orientation proper to the array; - and an analog/digital converter receiving, at input, the analog signal received, to deliver, at output, a corresponding digitized signal to a beam forming computer. The delay means are digital means, positioned at output of the analog/digital converter and typically comprise a digitally programmable delay generator comprising a programming input that receives a digital control word, defining the delay to be produced, from a pointing computer, a triggering input that receives pulses digitally representing the signal to be delayed and a signal output delivering the delayed signal pulses.

Abstract: This device includes: - first means 1, 2, 3, 4, 5, C0, D1, D2, C1, C2 for carrying out, in a first stage, a first analogue/digital conversion over > bits with n1 > conversion; - second means 1, 3, 4, 6, 7, C'0, D3, D4, C2 for carrying out, in a second stage, from the result obtained at the end of the first conversion, a second analogue/digital conversion over > bits with n2 = n - n1 or > conversion; - third means 8 for subtracting from the result obtained at the end of the first conversion the result obtained at the end of the second conversion. Application: analogue/digital coding.
