Radioastronomy Applications

Radio astronomy is that the study of celestial objects that give off radio waves. With astronomy, we study astronomical phenomena that are often invisible or hidden in other portions of the spectrum .In the astronomy program we specialise in techniques for designing the next generation of radio telescopes. Among other things, research is performed at large antenna arrays, the power to use pulsars for timing and navigation, and developing a low-frequency radio reflector. At low frequencies (below 30 MHz) the universe has never been properly mapped. However, this could provide accurate information about the young universe, when stars, galaxies and planets were formed. An earth-based radio reflector isn't ready to receive these very weak signals thanks to the opacity of the ionosphere and therefore the man-made static. So, we have to go into space. This next generation radio reflector is named OLFAR, the Orbiting Low Frequency Antennas for astronomy. Radio astronomers use different techniques to watch objects within the radio-frequency spectrum. Instruments may simply be pointed at an active radiator to research its emission. To "image" a neighbourhood of the sky in additional detail, multiple overlapping scans are often recorded and pieced together during a mosaic image.
