查询词典 helicopter

In this paper, the statistical characteristics of one plane and one helicopter's RCS dynamic measurement data are studied by using the χ^2 distributing, log-normal distribution and Rayleigh distributing model, along with the Kolmogorov fit test to goodness, the fitting results in some notableness level are acquired by using the three models for different aspect angles for two targets, and the degree of freedom distribution of χ^2 model in all aspect angles is obtained for two targets' RCS data.
