Abstract：In order to study the influence of different course short??cut and height on the dynamic RCS of air-craft and find out the universal model which can describe the dynamic RCS,the dynamic RCS of aircraft is statistically analyzed in this paper.By using a quasi??static analysis method,the dynamic RCS of aircraft is simulated at the different course short??cut and height,and the influence is analyzed respectively.Three sta-tistical fluctuation models are used to match the RCS statistic data and the difference between different course short??cut and height,and the difference of the modeling results are compared and inspected by Kol-mogorov??Smirnov test.The goodness??of??fit test results show Log??normal distribution is a universal distri-bution to describe the dynamic RCS beyond the limitation of course short and height.The results of this paper are of significance to the early warning and detection of non??cooperative target and provide a theoretic support to the advance of radar's function.
