Abstract
A near space atmospheric state simulation method and device based on the quantum walk comprises: firstly, 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; secondly, based on a one-dimensional topology network constructed by the bands, simulating interaction and transfer processes of gas molecules between the bands by quantum walk to obtain all possible near space atmospheric evolution models; then, 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 finally, 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.
