Analysis begin form the basic building block and extends to determine the radiation pattern, which is the most suitable array pattern and the ideal radio telescope structure. Firstly, the main aim was to introduce the diagonal horn to the focal planar scene. There have been some papers suggesting this horn is easy to manufacture and can give characteristic similar to the useful corrugated horn. In this research project it was important to get an aim which is clearly described. References was the next step, in order to start such a thesis a lot of research went in to finding everything to date on focal planar arrays.
Many papers exist leading in all directions with many explanations.
Firstly the telescope structure and the array format was determined. Next concern was the diagonal horn. This horn was analysed from Maxwell's equation all the way to the radiation pattern. Starting from this level allows all factors to be considered, even various modes. Conclusively, the radiation pattern was obtained using diffraction theory and Fast Fourier Transform computation.
