Calculation Method of Hypersonic Target Irradiance Based on Grid

摘要：

　　Hypersonic aircrafts produce large amounts of radiation during flight.The calculation of the radiation,which generated by the hypersonic vehicle,facilitates the design of the detection system.In order to calculate the irradiance of the target to the detector,a high-speed target irradiance calculation method based on grid is proposed in this paper,by accumulating the radiation of each grid cell on the target visible surface.On this basis,the simulation of the radiation of the typical flying head cone is carried out.The experimental result shows that the grid-based calculation method could reach higher computational accuracy than average temperature model,and can be applied to the accurate calculation of irradiance of high-speed target.
