How are radio waves generated?
Radio waves are generated by a disturbance of the electromagnetic field. Lightning for example gives out a pulse of radio waves over a broad range of frequencies, because of the ionization of the air. For communication & TV, an electronic oscillator is used to generate an electrical signal, and when fed to an antenna, this signal will generate radio waves. These particular radio waves are modulated to carry the information - speech - pictures etc.

How can radio waves be used to observe stars?
1) Any object that emits radiation (because of its temperature) will emit in all wavelengths, including visible light, infrared, radio waves, ultra-violet, etc. What changes is the proportion of each (which depends directly on the temperature). 2) The Earth's atmosphere is transparent to radio waves (meaning: it is easy to receive radio waves from space -- in general they are not blocked by the atmosphere). 3) It is easy to build a receiver that gives us the direction from which the radio waves are coming. We can draw maps of radio sources (the same way that taking pictures in visible light lets us draw maps of the visible stars).

What is the principles of radio direction finder?
Direction finding (DF) refers to the establishment of the direction from which a received signal was transmitted. This can refer to radio or other forms of wireless communication. By combining the direction information from two or more suitably spaced receivers (or a single mobile receiver), the source of a transmission may be located in space viatriangulation.
