dc.description.abstract	Some basic concepts in use for making astronomical observations at radio wavelengths are introduced. In particular the importance of phase information for imaging in radio astronomy is highlighted. Using simple examples it is demonstrated how phase information is much more essential than that even of amplitude for an image reconstruction from its Fourier components.	en
