Requirements already exist for antennas in excess of 10m in diameter for remote sensing from space [1]. Aperture synthesis is a technique for overcoming the limitation that a large antenna aperture ...

Through this computational process, known as 'aperture synthesis', the virtual separate antennas are linked together to form a large 'synthetic' antenna of up to 15 kilometres in length. The effect is ...

The mission makes global observations of the Earth's surface soil water content and the salt in the oceans. A greater ...
