  • SNIFT | TICRA
    of the measuring probe provided it is rotationally symmetric in spherical wave terms the probe pattern contains only m 1 harmonics The computed field will in all points have an accuracy of 70 dB or better relative to the isotropic level of the field provided that both the input field is determined with the same accuracy and the sampling theorem is fulfilled Full sphere measurements is not a requirement partial

  • Design optimization of reflectarrays | TICRA
    have been investigated To this end several benchmark reflectarrays that exaggerate some of the sources of error were designed manufactured and measured at the DTU ESA Spherical Near Field Antenna Test Facility The results of this ESA ESTEC study will eventually be fully incorporated into TICRA s software packages which greatly enhance the possible modeling scenarios Typical examples include combinations of solid reflectors and reflectarrays design and optimization of contoured

  • Development of fast and accurate horn design software | TICRA
    way for winning a contract with ESA to develop a program for telecommunication and tracking multi mode horn design optimization TICRA had the pleasure of engaging Thales Alenia Space France as sub contractor thereby benefitting from their enormous expertise in practical hardware developments for space applications With the new broadband telecommunications services the satellites will generate very narrow multiple spot beams with stringent requirements imposed on the pointing accuracy This is typically obtained using a reflector antenna where the feed horns in addition to the primary telecommunications signal also have so called tracking capabilities The developed software tool enables the design of these high efficient multi mode feed horns simultaneously optimizing telecommunication and tracking performances Optimized profile of the corrugated horn shown in photo above The innovations have focused on the combination of fast and accurate feed horn analysis with a very powerful optimization framework where the feed geometry can be optimized in an hierarchical way starting from a high level model using very few parameters and ranging to a fine grained model with a large number of degrees of freedom In order to validate the software tool a feed horn was first designed using the new software tool then

  • Planck Telescope In-flight Retrieval | TICRA
    of the shape of the reflector surfaces is performed by an optimization in which surface perturbations described by Zernike modes are optimized in order to fit the given patterns The field is determined by Physical Optics and the optimization is based on least squares deviation using one of the best algorithms for non linear least squares optimization In the optimization the determined patterns are fitted to the measured patterns within the regions in which the measured patterns are higher than the noise level C ESA The goal of the Planck Space Telescope is to observe the cosmic microwave background radiation with an unprecedented accuracy Therefore it is very important to know the patterns of the antenna with a correspondingly high accuracy The Telescope is an aplanatic reflector system equipped with 47 microwave detectors in RF bands from 30 GHz to 857 GHz positioned over the curved focal plane of the antenna RF measurement could not be performed with sufficient accuracy on ground as the working temperature of the telescope is 40 K with the detectors cooled to 0 1 K In orbit measurements are thus requested TICRA developed a technique for in flight testing of the antenna system The beams
