... COMPUTER SIMULATION OF RADIOWAVE MULTIPLE SCATTERING EFFECTS IN IONOSPHERE USING MONTE-CARLO METHOD . ... Distribution of reflected radiation on the ground is computed. ... Such influence can be remarkable if the scattering is multiple, i.e. the optical thickness for the scattering process is considerably greater than a unit. ... Radiation energy transfer in the slab is modeled by distribution of some particles carring small portions of radiation energy. ... The isotropic plasma approximation is...

... The source exhibits a mas-scale structure which, according to the USNO multi-epoch monitoring at 2.3 and 8.4 GHz over the period from 1994 July through 1998 April, undergoes considerable changes in the brightness distribution and positions of the major structural features. Our image is qualitatively consistent with the structural pattern of the source. ...
