Abstract: A method of measuring distance of a target by a pulse emitter and a matrix detector includes spatial mini-detectors coupled to capacitors whose duration of integration is controlled by a polarization of the mini-detectors. The method includes: A) determination of the direction of the target with respect to a known direction of the emitted pulses, and of a first integration period during which an echo of a pulse backscattered by the target is detected by the detector, determining a first distance slice in which the target is situated, B) reduction of the first distance slice in the course of successive telemetry iterations, that is to say emission of a pulse by the emitter and testing of detection of an echo by the detector, which are carried out: on the basis of the first integration period, by dichotomy of the duration of integration, and based on the detection of an echo of the target, a second distance slice in which the target is situated and included in the first distance slice, being determined on completion of this step, C) reduction of the second distance slice in the course of successive telemetry iterations which are carried out: on the basis of the integration period arising from step B, by variations of the position of the integration period, with constant durations of integration, and based on the detection of an echo of the target, a third distance slice in which the target is situated and included in the second distance slice, being determined on completion of this step.

Abstract: A fuze for detecting an obstacle in proximity, an obstacle in proximity defined as being an obstacle exhibiting a minimum distance from the fuze, wherein the fuze comprises at least: an emission device emitting a light beam directed forward of the fuze; a reception device detecting the luminous fluxes in a cone directed forward of the fuze, the light beam and the cone having relative orientations such that they cross one another; a detection volume being the volume where the light beam crosses the cone so that when an obstacle is in the detection volume, the light emitted by the emission device is backscattered toward the detection device, an obstacle in proximity being detected by detecting the maximum of backscattered power, the reception cone is centered on the axis of the fuze.

Abstract: A data communication systems including a main channel that includes means for sending a signal, means for transmitting the signal and means for receiving the signal, the sending means sending signals at a known frequency. The communication system includes a stand-by channel that includes the following devices: a device for temporarily stopping the sent signal at instants known as stopping instants for a constant length of time that corresponds to the sending of a first determined number of sent signals, the stopping instants corresponding to temporal coding of a stand-by signal; a device for summing the amplitudes of the received signals, the summing being carried out on a second determined number of received signals; a device for temporally determining the instants corresponding to the minima of the summed signal, the determined instants having the same temporal coding as the stopping instants.

Abstract: A device for measuring a distance of a target by means of a telemeter comprises: a laser pulse emitter; a receiver of the laser echoes backscattered by the target, comprising, a spatial detection device which comprises at least one photodiode set up as integrator and is able to provide a spatial signal, and a temporal detection device which comprises at least one photodiode coupled to a transimpedance circuit and is able to provide a so-called temporal signal, means of processing of the spatial signal and of the temporal signal, comprising a unit for calculating the distance of the target, the temporal signal being in the form of a data frame which is the recording of data detected over a predetermined duration. The means of processing comprise: means of post-integration of temporal signals, linked at output to the unit for calculating the distance of the target, linked to the spatial detection device and to the temporal detection device, means for selecting the temporal signals to be transmitted to the post-integration means, as a function of the spatial signal.
