Imaging the sky with radio waves- a large aperture telescope is ‘synthesized’ in software

by sampling the wavefront with small antennas

After 12 hours, the WSRT becomes a telescope 3 km in

diameter, with images100x sharper!

The LOFAR opportunity

•A new concept for a radio telescope; •Using many (25.000) radio antannas;•Using a extremely powerfull central processor;•Covering a large area;•Leading to a software telescope with the capability to measure in real time

Wide Area Sensor Networks use large numbers of cheap

sensors, like the LOFAR antennas….

The development of (wireless) sensors forfighting Phytophtora

… and the vibration sensors for geophysical

research.

Radio antennas are “radio sensors”)

So: other sensor applications are possible

LOFAR is a multidisciplinairy adaptive wide area sensor network
