Introduction to Radio Astronomy
IEEE MTT-S, Caltech Mixed-Signal, RF & Microwave Seminar
Radio Astronomy grew from an accidental discovery in 1932, virtually ignored for years, to a prolific window to a previously invisible universe, producing four Nobel Prizes. This seminar will introduce exciting areas of current research and the technology that drives them. Most new radio telescopes utilize array techniques and the fundamental relation between the image of radio wave intensity in the sky and the correlation function measured between spaced antennas on the earth will be discussed. A movie of radio sky images from a current low frequency array at the Caltech radio observatory will be presented. A major new international instrument, the Square Km Array, is now in the detailed design phase and alternative next steps in the US will be described along with the current microwave technology developments in my group at Caltech.
