LOGICIELS DE MESURE ET DE TRAITEMENT DE DIAGRAMMES DE RAYONNEMENT D'ANTENNES : APPLICATION A LA RECHERCHE DU CENTRE DE PHASE Joël KORSAKISSOK – jkorsa@silicom.fr - Silicom Grand Sud Ouest : 5, Avenue Albert Durand – 31700 BLAGNAC Daniel BELOT – Daniel.belot@cnes.fr - Jean-Marc LOPEZ –jean-marc.lopez@cnes.fr CNES : 18, Avenue Edouard Belin – 31401 TOULOUSE Cedex 9 CONCLUSION Dans le domaine de la métrologie antennes, il est nécessaire de maîtriser plusieurs méthodes pour affiner la précision de mesure: correction de centre de phase, corrections liées aux imperfections de la chaîne de mesure, de la chambre anéchoïque, du moyen de mesure (positionneur, logiciel de mesure à la volée), etc. Fig 7 : Ecran d’affichage des résultats de calcul de centre de phase dans SAMS DA Il importe de quantifier chacune des erreurs induites correspondantes (ou, au minimum de trouver un majorant), voire de mettre en oeuvre des corrections, pour être en mesure de donner une estimation de la précision de mesure réalisée.

BACK Low Phase Noise Optical Links for Reference Frequency Distribution in Satellite Payloads Gianandrea QUADRI, Horacio MARTINEZ-REYES, Benoit BENAZET (1) , Olivier LLOPIS LAAS-CNRS, 7 Avenue du Colonel Roche, 31077 Toulouse, Cedex 04, France (1) Alcatel Space, 26 av. J. F. Champollion, B.P. 1187, 31037 Toulouse, France Abstract — Various circuits dedicated to high spectral purity signal transmission using fiber optics are presented. Three application types are investigated : reference frequency distribution at 10 MHz, IF distribution at 800 MHz and microwave synthesized signals at 3.5 GHz. The reception circuit is an optically synchronized oscillator, which provides a good signal conditioning far from the carrier while maintaining the high input signal quality close to the carrier. I. INTRODUCTION Fiber optics constitutes an attractive alternative to conventional wiring for numerous analog applications. Indeed, in addition to its small size and low mass, the fiber does not interfere with electronic devices and provides an excellent isolation of the transmitted signal. One of the targeted application of our work is the reference frequency signal distribution to various subsystems of a telecommunications satellite. Another application could be remote antenna synchronization and control. However, to meet our system requirements, the fiber optics link should not degrade the signal quality, and particularly its phase noise. To this purpose, the optically synchronized oscillator [1,2] is an efficient approach which naturally filters the signal far from the carrier, thus removing the additional noise due to the optical link. Moreover, an optically controlled oscillator delivers a constant output power, which is an interesting feature for a clock or reference frequency delivering network. Different types of optically synchronized oscillators may be investigated. The simplest one uses a conventional photodiode to detect the amplitude modulated optical signal, and the resulting microwave signal is used in a classical injection lock of a microwave oscillator, or as a reference signal in a PLL. In this case, we speak about an indirect optically synchronized oscillator. Another possibility is to realize the oscillator with a transistor sensitive to the optical power (photo-transistor) and thus to control directly the oscillator amplifying element. In this study, various solutions are investigated for a low phase noise optical link at 10 MHz, 800 MHz and 3.5 GHz. Indirect synchronization has been chosen for the two lower frequencies, and both indirect and direct synchronization have been investigated at 3.5 GHz using two types of active devices : an InP based bipolar phototransistor (photo-HBT) [3], and an InP based HEMT device [4]. The application goal for the 10 MHz link is the reference frequency distribution in a telecommunications satellite. The signal from the ultra stable quartz crystal oscillator should be transmitted with no degradation of its phase noise, and this is a very stringent requirement. The 800 MHz application is also in the field of telecommunications satellites, and corresponds to an intermediate frequency in the satellite. The 3.5 GHz frequency is a first attempt to compare the different approaches for high spectral purity microwave signal distribution. The application is not clearly defined today, but it could be in the field of active antennas. II. PHOTO-OSCILLATOR ; THEORY The indirect optical injection locking can be efficiently described by combining the classical noise modeling of an optical link [5,6] to the theory of injection locked oscillators [7,8]. The only questionable point is probably in the interaction between the two systems : has the photodiode (or its associated amplifier) an effect on the oscillator noise ? But if the two systems are isolated in some way from one to another, this approach should apply. The following equation (from Kurokawa’s theory [8]), is an expression of the output phase noise spectral density of a synchronized oscillator, versus the input signal phase noise Sφ input, the free running oscillator phase noise Sφ free, the locking bandwidth flock and the offset from carrier fm. 2 ⎛ f m ⎞ ⎜ ⎟ ⎜ f ⎟ 1 ⎝ lock ⎠ Sϕ = ⋅ S S sync ϕ + ⋅ 2 input 2 ϕ free ⎛ f m ⎞ ⎛ f m ⎞ 1 + ⎜ ⎟ + ⎜ ⎟ ⎜ f ⎟ 1 ⎜ lock f ⎟ ⎝ ⎠ ⎝ lock ⎠
