摘要: The invention relates to a FMCW lidar imager system with improved distance resolution. The imager system 1 comprises a reflector 42 configured to reflect, in the direction of the scene 2, a portion Sor,nc of the backscattered object signal Sor, which portion has not been collected by the collecting optical element 41. Thus, the collected portion Sor,c of the backscattered object signal Sor is formed from first light beams Sor,c(1) that have not been reflected by the reflector 42 and from light beams Sor,c(2) that have been reflected by the reflector 42. The heterodyne signal Sh therefore has a principal component Sh(1) associated with the light beams Sor,c(1), and a secondary component Sh(2) associated with the light beams Sor,c(2). The processing unit 60 is configured to determine the distance zsc of the scene 2 on the basis of a beat frequency fb(2) of the secondary component Sh(2) of the heterodyne signal Sh.

摘要: The present description concerns a method of processing by a radio transmitter/receiver (12) of a radio signal (SR) comprising a telecommunications signal disturbed by pulses of a radar signal, the method comprising the steps of: estimating the instantaneous power of the pulses, estimating the ratio of the average power of the telecommunications signal to the instantaneous power of the radar pulses, and modifying the radio signal at the locations of the radar pulses when said ratio is smaller than a threshold.

摘要: A method for executing a function, secured by temporal desynchronization, includes when a first legitimate instruction is loaded, noting the opcode of this first legitimate instruction, then constructing a dummy instruction on the basis of this noted opcode, the dummy instruction thus constructed being identical to the first legitimate instruction except that its operands are different, then incorporating the dummy instruction thus constructed into a sequence of dummy instructions used to delay the time at which a second legitimate instruction is executed.

摘要: A transmit-array collimating assembly, this collimating assembly being able to convert a first electromagnetic wave radiated from a first focal point and in a first frequency band, into a plane electromagnetic wave of same frequency radiated in a preset first direction, and to convert a second electromagnetic wave radiated from a second focal point and in a second frequency band, into a plane electromagnetic wave of same frequency radiated in the same preset first direction, first and second primary radiating elements solely connected to first and second output ports of a transmitting module, respectively. The first and second primary radiating elements are positioned so as to radiate the first and second electromagnetic waves from the first and second focal points, respectively.
