统计动差
We suggest a new method of statistic modeling, in which the first nth central moments of real target's radar cross section ( RCS) are used to characterize the target, and the Legendre orthogonal polynomials are used to reconstruct the PDF of the target's RCS.
本文提出了一种新的统计模型,它以统计量的各阶中心矩来表征目标,然后用Legendre正交多项式系来再现其概率密度函数。
