Abstract: | Extensive computer simulations aimed at testing a hypothesis that impact craters may explain the scaling behaviour of surface
spectra are presented. The simulations show that indeed crater effects alone may explain the spectral scaling of Mars’ topography
revealed from MOLA data. The range of the scaling exponents obtained for a wide range of simulation parameters does not exceed
the limits observed for Mars. The simulations suggest that the shape of large craters is the key factor leading to the two
scaling ranges in the surface spectra. Particular values of the scaling exponents may additionally depend on the depth-diameter
relationship and the crater size distribution. |
