针对运动目标 R C S 变化规律,提出将目标 R C S 变化序列分解为确定变化序列( Certain Variation Sequence, C V S) 和随机变化序列( Random Variation Sequence , R V S) 的设想.其中 C V S 敏感于姿态,在姿态域表现为丰富的细节特征,而 R V S则表现为近似正态分布的非平稳随机过程.本文用实验数据证明这两种变化序列均具有分形的特征.由以上的分析结果,利用分形迭代函数系统将这两种变化序列进行有效分解,其分解效果明显优于传统的滤波方法.
In this paper
we analyze the Radar Cross Section(RCS) sequence while target is moving
then propose that it is composed by Certain Variation Sequence (CVS) and Random Variation Sequence (RVS).We can testify that they have the fractal features
and as a result a fractal filter based on Iterate Function System (IFS) is presented.The result shows the decomposition is better than band passed filter.
