 The goniopolarimetric methods, also known as direction finding, are powerful methods which are used to obtain the intensity, the polarization, and the position of the low-frequency radio sources in the sky plane. These methods have been applied to several auroral sources and to the solar wind sources. The results obtained by these methods have allowed us to drastically improve our understanding of the processes occurring in the concerned regions. These methods are only valid for point source, or weak extended sources, whereas in many cases extended or multiple sources are expected. Some methods allow to obtain the characteristic size of the source, but not its shape or the intensity distribution inside it. In the present paper a method is proposed which can determine the intensity distribution inside an extended, but one-dimensional source and which can be applied to observations of two close sources. Application to simulated auroral and solar wind emissions are also presented.
