1.实验目的：绘制分形图案并分析其特点。  2.实验内容：绘制Koch曲线、Sierpinski三角形和树木花草图形，观察这些图形的局部和原来分形图形的关系。  3.实验思路：利用函数反复调用自己来模拟分形构造时的迭代过程，当迭代指标n为0时运行作图操作，否则继续迭代(1. Purpose: Draw fractal patterns and analyze their characteristics. 2. Experiment: Draw Koch curve, Sierpinski triangle graphic flowers and trees, observe the relationship between the local and original graphics fractal graphics. 3. Experiment idea: using the function calls itself repeatedly to simulate the iterative process when the fractal structure, when the iteration index n is plotted 0:00 run, otherwise continue iterating)

对海杂波的仿真，考虑了相控阵雷达威力范围、随着距离增大而引起的强度衰减、杂波类型、对海杂波的抑制等多个方面，对雷达总体设计人员有一定的帮助，值得学习和借鉴。(simulate sea clutter with consideration of many aspects, such as sphere of action of PAR radar, strength attenuation resulted from extending range, type of clutter and inhibition of sea clutter)
