中文摘要：
高分辨力雷达体制下，杂波散斑分量与调制分量更适合用广义Gamma分布模型描述，在此基础上，建立了广义复合杂波模型表达式，随后研究了在热噪声情况下的广义杂波分布模型；然后通过对模型选取特定参数，得到了广义K分布表达式，同时分析了取不同参数广义K分布时与经典杂波概率分布的联系；最后研究了上述有关杂波模型的统计特性，进而得到了参数估计的基本方法。进行了仿真实验，验证了结论。
英文摘要：
Under system of high resolution radar, it is more suitable for the generalized gamma probability density function （GP-pdf） that characterizes the speckle component and modulation component of the clutter. The expression of generalized compound （GC） pdf is derived based on this. Furthermore,its expression of incorporation with thermal noise is also discussed. Chosen special parameters, the generalized k （GK）pdf model is established. It analyzes the relation between the classical clutter models and GK-pdf model possessed by variety values of parameters. The statistics characteristic of the clutter models above-mentioned are researched, basic method of parameter estimation is derived. The simulation results show the conclusion in this paper.
