Patent
Thales Alenia | Date: 2017-04-05

The invention relates to an antenna adapter (840) which is intended for being placed between an antenna (830) and a receiving channel (850). The adapter includes: a first conductive wire (806) crossed by an external current (iext) corresponding to a signal supplied at the output of the antenna, the first wire creating an external magnetic field in the vicinity thereof; and a magnetometric sensor (810), placed in the vicinity of the first conductive wire, sensitive to a flux of the external magnetic field and capable of generating an output signal corresponding to the external current.

The invention relates to a current-detection device (300) which is characterised in that it includes: a first conducting wire (306) crossed by an external current (iext) to be measured, said first wire creating an external magnetic field (Bext) in its vicinity; and a magnetometric sensor (310) positioned in the vicinity of the first conductive wire, said sensor being sensitive to a flux of the external magnetic field and capable of generating a measurement signal corresponding to the external current.


This determination method for determining a wrong synchronization including the steps of determining an ad hoc correlator corresponding to the value of correlation between the received signal and the local signal, and determining N additional correlators corresponding to the values of correlation between the received signal and an offset signal, each offset signal including a spreading code that is offset in relation to the local spreading code, and determining a value for the amount of inconsistency between the frequency of the local carrier wave and the frequency of the local spreading code; if the value of inconsistency is higher than a predetermined threshold value of inconsistency, determining a wrong synchronization; otherwise, determining an indicator of wrong synchronization as a function of the correlators determined, comparing the indicator of wrong synchronization with at least one threshold value, determining a wrong synchronization based on the result of the comparison.


The radar device comprises at least: - an antenna (21) operating at the polarisation of marine navigation radars and comprising at least three receiving channels in the horizontal plane, - for each channel, a receiver (22), the bandwidth of which is tunable in the frequency range of said marine navigation radar; - a processing unit (23) simultaneously making a plurality of detections, each adapted to a type of received signal. The processing unit compares parameters of the detected radar signals with standard parameters defining marine navigation radars in order to deduce therefrom the nature of the vessels fitted with the radars emitting said signals.


A piece of airborne optoelectronic equipment (EO, EO1, EO2) comprising: - at least one image sensor (CI1, CI2), designed to acquire a plurality of images (IMR1, IMR2) of a region (RS) flown over by a carrier (PO1, PO2) of said equipment; and - a data processor (PD) configured or programmed to receive at least one so-called acquired image and transmit same to a display device (EA); characterised in that said data processor is also configured or programmed to: - access a database (BD) of images of said overflown region; - extract, from said database, information making it possible to synthesise a virtual image (IMV) of said region that is viewed by an observer located at a predefined observation point and watching, with a predefined field of view, along a predefined line of sight; - synthesise said virtual image and; - transmit same to said or to another display device. The invention also relates to a method for using such a piece of equipment.

The invention relates to a method for texturing a semiconductor substrate (1), comprising steps consisting in: forming a plurality of cavities of random shapes, depths and distribution, in an etch mask (2), by means of non-homogeneous reactive-ion etching, forming a first rough random design; and etching the substrate using the etch mask, by means of reactive-ion etching, in such a way as to transfer the first rough random design into the substrate and to produce a second rough random design (200), comprising cavities (20) of random shapes, depths (d2r) and distribution, on the surface of the substrate.


Patent
Thales Alenia | Date: 2017-04-05

The invention relates to a sensor (10) which includes a magnetic sensor (12) generating a response signal (V) when plunged into an external magnetic field (Bext) creating an external flux (ext) through said sensor. Said sensor includes: a control circuit (14) taking the response signal from the sensor as input and generating a feedback current (iCR) as output; and a conductive wire (16) arranged in the vicinity of the sensor and connected to the output of the control circuit, the wire having the feedback current passing therethrough, the circuit and the conductive wire being such that a magnetic feedback field (BCR) is created in which the flux through the sensor substantially compensates for the external flux at each instant, an output signal of the sensor being made up of the feedback current.
