针对非相关K杂波仿真问题，研究了一种基于三次样条插值方法新的杂波仿真方法。根据非相关杂波的产生原理，用三次样条插值方法拟合累积分布函数与杂波幅值之间的关系,从而通过产生(0,1)之间随机变量得到K分布积累函数值；再根据三次样条插值函数拟合的K分布杂波累积分布函数与K分布杂波序列之间关系得到非相关K杂波序列。理论分析和仿真结果表明了该方法的有效性和普适性。

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.
