The invention discloses a Geant4-based
solar flare X-
ray full-link
simulation method and
system, and belongs to the technical field of space
satellite detection and numerical
simulation. The method comprises the following steps: building a Geant4-based high-performance
hybrid parallel computing platform; a layered
magnetization solar
atmosphere model is constructed based on the platform, a physical process
list is configured, and a high-energy
electron particle source is generated; through a
ray tracing
algorithm and a user-defined stepping action module, tracking
simulation is carried out on transmission, scattering and polarization evolution of X-rays in the layered magnetized solar
atmosphere; and through a pixelated imaging and data output module, the
photon information is mapped to imaging planes of a plurality of virtual detectors, and X-
ray imaging pictures, energy spectrums and polarization degree data of different observation visual angles are output. The problems that an existing model is not matched with multi-
satellite stereoscopic
observation data,
Compton scattering details are missing, polarization information is insufficient and calculation efficiency is low are solved, and an effective tool is provided for analysis and simulation of multi-
satellite combined
observation data.
