Description
technical field [0001] The invention relates to the technical field of space detection, in particular to a calibration system and method for a space neutral atom detection instrument. Background technique [0002] Advances in space environmental science research show that space weather changes, especially magnetospheric substorms and magnetic storms, are characterized by global evolution. The plasma detection in the satellite local space only reflects the physical characteristics of the area the satellite passes through, and has both spatial and temporal variation factors. Spatial probing requirements for evolving physical signatures. For particle response energy ranges and specific space regions, the development of particle imaging detection technology with telemetry function is an urgent requirement for space physics research and space weather environment monitoring. [0003] At present, neutral atom imaging technology is a high-tech application in space exploration in r...
