Near space atmospheric state simulation method and device based on quantum walk

A near space atmospheric state simulation method based on quantum walk, comprising the following steps:

• (i) based on a characteristic of a near space atmosphere changing along with latitude, dividing a study region into a plurality of bands according to the latitude;
• (ii) based on a one-dimensional topology network constructed by the bands in the step (i), simulating interaction and transfer processes of gas molecules between the bands by quantum walk to obtain all possible near space atmospheric evolution models;
• (iii) screening for actually existing evolution models in each of the bands based on stepwise regression by taking observed atmospheric density data as constraint conditions;
• and
• (iv) constructing a mapping mechanism between a plurality of near space atmospheric evolution models and atmospheric density parameter values to achieve simulation and optimization of near space atmospheric states, which realizes working time setting and reconnaissance range control for a space vehicle.
