interferometryEMI

I am Hauyu Baobab Liu, an associate professor at the Department of Physics of National Sun Yat-sen University, More details about me can be found here, Here is my EMI lecture on radio interferometry at National Sun Yat-sen University (NSYSU) To my understanding, I have sold the material I am sharing to the Ministry of Education (i.e., they own the license). I have a quite poor understanding about such legal issues, unfortunately. But I know I can feel free to share these materials on my webpage; you can also watch and share them for free. If you would like to modify or directly re-use the material, you may need to consult them, although I also do not know how. Please feel free to contact me regarding this. I can help you consult them.

This is a preliminary version of the first half of the material. There may be something wrong. If you see that, it would be very much appreciated if you would like me know. I will correct it.
