三次样条插值产生非相关K分布杂波新方法
Novel method of generating non-correlated K distribution clutter using cubic spline interpolation
摘要
Abstract
Aimed at the simulation of non-correlated K distribution clutter, this paper studies a novel method for clutter simulation based on cubic spline interpolation. According to the principle of non-correlated clutter generation, it fits the relations between the function of accumulative distribution and the clutter amplitude using the cubic spline interpolation method, thus obtaining the K distribution accumulation function values with through generating the random variables in interval of (0,1). And it obtains the non-correlated K clutter sequence in terms of the relations between the clutter accumulative distribution function with K distribution fitted by cubic spline interpolation function and K distribution clutter sequence. Theoretical analysis and simulation results show that this proposed method is of effectiveness and availability.关键词
