Esta tesis analiza el caso de desarrollo de radares secundarios y primarios en Argentina a partir del año 2003, explicando las circunstancias por las cuales se decidió optar por el desarrollo nacional de esta tecnología y dejar de lado más de cincuenta años de dependencia tecnológica referida al control del tráfico aéreo y la vigilancia y control del espacio aéreo. El caso de desarrollo de radares en Argentina es analizado desde la noción de co-creación entre tecnología y sociedad propio del conductivismo social de la tecnología (COST). Se espera que el caso analizado sea de utilidad a diversos actores.
This thesis analyzes the case of development of secondary and primary radars in Argentina since 2003, explaining the circumstances for which it was decided to opt for the national development of this technology and setting aside more than fifty years of technological dependence related to control of air traffic and surveillance and control of air space. The case of radar development in Argentina is analyzed from the notion of co-creation between technology and society of the social conductivism of technology (COST). It is expected that the analyzed case will be useful to different actors.

The Southern Argentina Agile Meteor Radar (SAAMER) was installed at Rio Grande on Tierra del Fuego (53.8°S, 67.8°W) in May 2008 and has been operational for ∼24 months. This paper describes the motivations for the radar design and its placement at the southern tip of South America, its operating modes and capabilities, and observations of the mean winds, planetary waves, and tides during its first ∼20 months of operation. SAAMER was specifically designed to provide very high resolution of large-scale motions and hopefully enable direct measurements of the vertical momentum flux by gravity waves, which have only been possible previously with dual- or multiple-beam radars and lidars or in situ measurements. SAAMER was placed on Tierra del Fuego because it was a region devoid of similar measurements, the latitude was anticipated to provide high sensitivity to an expected large semidiurnal tide, and the region is now recognized to be a “hot spot” of small-scale gravity wave activity extending from the troposphere into the mesosphere and lower thermosphere, perhaps the most dynamically active location on Earth. SAAMER was also intended to permit simultaneous enhanced meteor studies, including “head echo” and “nonspecular” measurements, which were previously possible only with high-power large-aperture radars. Initial measurements have defined the mean circulation and structure, exhibited planetary waves at various periods, and revealed large semidiurnal tide amplitudes and variability, with maximum amplitudes at higher altitudes often exceeding 60 m s−1 and amplitude modulations at periods from a few to ∼30 days.
