摘　　要：China’s Mars exploration mission has stimulated tremendous interest in planetary science exploration recently.To propose potential scientific research projects,this study presents a concept simulation for the measurement of Martian atmospheric winds using the Doppler Michelson interferometry technique.The simulation is based on the satellite instrument initially designed for the Dynamic Atmosphere Mars Observer(DYNAMO)project to measure vertical profiles of winds from the 1.27μm airglow observations in the Martian atmosphere.A comprehensive DYNAMO measurement simulation forward model based on an orbit submodel,an atmospheric background field submodel,and an instrument submodel is developed using the Michelson equation.The simulated interferogram signal over the field of view(FOV)calculated by the forward model is associated with the filter transmittance function,column emission rate of airglow,wind velocity,temperature,and the Michelson phase.The agreement between the derived atmospheric signals from the simulated interferogram without altitude inversion and the input parameters used to initiate the forward model confirms the validity of the forward model.
