Since 1993 ESA has been conducting several feasibility studies and breadboarding activities for the development of a "Microwave Imaging Radiometer with Aperture Synthesis", known as MIRAS. This Earth-observation instrument is intended particularly for the measurement of soil moisture and ocean salinity on a global scale. The relevance of these two geophysical parameters has been repeatedly emphasised by the scientific community and MIRAS could eventually form the core of an ESA Earth Explorer mission devoted to the global measurement of these two parameters.  2, record 1, English, - microwave%20imaging%20radiometer%20with%20aperture%20synthesis

Traditional methods for acquiring topographic data typically rely on aerial photogrammetry, where measurement of the terrain surface below forest canopy is difficult and error prone. The recent emergence of airborne P-band interferometric synthetic aperture radar(IFSAR), a high-resolution, microwave remote sensing technology, has the potential to provide significantly more accurate terrain models in forested areas. Low-frequency, P-band radar energy physically penetrates through the vegetation canopy and reflects from the underlying terrain surface, allowing for accurate measurement of the terrain surface elevation even in areas with dense forest cover.  3, record 2, English, - interferometric%20synthetic%20aperture%20radar

Un radar à synthèse d'ouverture (SAR) est un radar imageur qui effectue un traitement des donnés reçues afin d'améliorer la résolution azimutale. Le traitement effectué permet d'affiner l'ouverture de l'antenne. On parle donc de synthèse d'ouverture. D'où le nom de ce type de système. Les radars à synthèse d'ouverture sont donc à opposer aux «radars à ouverture réelle» (RAR ou real aperture radar en anglais) pour lesquelles la résolution azimutale est simplement obtenue en utilisant une antenne d'émission/réception possédant un lobe d'antenne étroit dans la direction azimutale.  2, record 2, French, - radar%20interf%C3%A9rom%C3%A9trique%20%C3%A0%20synth%C3%A8se%20d%27ouverture

L'émergence récente des données interférométriques radar aéroporté à synthèse d'ouverture en bande P (IFSAR), une technologie de télédétection micro-onde à haute résolution, pourrait fournir des modèles d'altitude significativement plus précis dans les zones forestières. L'énergie à basse fréquence du radar en bande P pénètre physiquement à travers le couvert de végétation et est réfléchie par la surface sous-jacente du terrain permettant la mesure précise de l'altitude à la surface du terrain, même dans les zones de couvert forestier dense.  3, record 2, French, - radar%20interf%C3%A9rom%C3%A9trique%20%C3%A0%20synth%C3%A8se%20d%27ouverture

The method of enhanced microwave scattering is based on the measurement of the signal, which is Back Scattered(BS) in the Upper Hybrid Resonance(UHR) vicinity. At first this technique was applied to small-scale oscillations and waves investigations in quiet plasma of linear laboratory devices.
