| Abstract: | The fundamental principle of the lunar low-frequency radio telescope is introduced in this paper.The advantage and impedance characteristics of the used dipole antenna are discussed.The patterns of antenna at different frequencies and heights from ground are obtained by the planewave exoansion with the Geometry optics instead of the traditional Sommerfrld integral method.The results indicate that sensitivity is the best above 1.5~2.5 meter from ground in the range of 1 MHz~30 MHz.The conclusions can help to choose the optimum design finally. |
