A modified and more accessible calculation algorithm is proposed to solve the problem of infrared radiation analysis of hypersonic target.Basing on the classic aerodynamic heating theory,considering key atmosphere environment′s influence,the algorithm chooses the altitude as modification parameter which is deduced with local density and temperature,and finally achieves the calculation model of aerodynamic hearting temperature of hypersonic reentry target.With the model,the infrared radiation of a typical hypersonic reentry flight setting is calculated and analyzed.
