摘要： Un récepteur à large bande passante servant à convertir un signal d'entrée de haute fréquence (36) en des impulsions de sortie (50) produit l'expansion de la largeur d'une impulsion de sortie (50) pour permettre le traitement des impulsions à l'aide d'un équipement conventionnel à des cadences de traitement plus lentes. Un oscillateur local de balayage (42) module en fréquence le signal d'entrée (36) pour créer un signal modulé en fréquence qui est comprimé en une impulsion par une ligne de retard à dispersion (40). La largeur de l'impulsion de sortie (50) est augmentée en produisant une non-correspondance ou différence dans les pentes fréquence/temps (52, 54) de l'oscillateur et de la ligne de retard à dispersion. La différence de pente est obtenue à l'aide d'un générateur de fonction (58, 68) qui maintient la pente fréquence/temps (52) de l'oscillateur local de balayage (42) à une valeur différente de celle produite par la ligne de retard à dispersion (40).

摘要： An antenna device includes an array antenna 2 formed of five radiating elements 21 to 25 arrayed on a dielectric substrate 1, and a feeder circuit 3 that feeds a high frequency signal to the radiating elements 21 to 25 making up the array antenna 2. The five radiating elements 21 to 25 are arrayed on a first straight line L1 drawn in a direction horizontal to the ground, and an excitation voltage of the radiating element 23 positioned at the center of the array is set to be 2.2 times or more an average value of excitation voltages of the other radiating elements 21, 22, 24, and 25.

摘要： Broadband signal transmissions may be used for object detection and/or ranging. Broadband transmissions may comprise a pseudo-random bit sequence or a bit sequence produced using, a random process. The sequence may be used to modulate transmissions of a given wave type. Various types of waves may be utilized, pressure, light, and radio waves. Waves reflected by objects within the sensing volume may be sampled. The received signal may be convolved with a time-reversed copy of the transmitted random sequence to produce a correlogram. The correlogram may be analyzed to determine range to objects. The analysis may comprise determination of one or more peaks/troughs in the correlogram. Range to an object may be determines based on a time lag of a respective peak.

摘要： An analog front end for a radar system and method of operation are described. A transmitter circuit transmits a radar signal and a receiver circuit receives and processes a reflected radar signal and outputs a received radar signal. A timing circuit controls operation of the transmitter circuit and the receiver circuit and outputs a valid data signal indicating whether the receiver circuit will be receiving the reflected radar signal. A converter converts the received radar signal and outputs digital data. A serialising circuit receives the digital data and supplies a serial data stream including the digital data for a data processing device. The valid data signal is also communicated to the converter to cause the converter to output a bit pattern corresponding to a code word when the valid data signals indicates that the receiver circuit will not be receiving the reflected radar signal and to output a bit pattern corresponding to a data word including radar data when the valid data signals indicates that the receiver circuit will be receiving the reflected radar signal.
