In this work,based on the principle of microdoppler,the mathematical model between missile and decoy is constructed,and characteristics in microdoppler are analyzed through simulation,thus distinguishing the target from heavy decoys and the missile.It offers a new reassuring way to the discrimination of the real or false targets.Keywords : target recognition;warhead;decoy;microdoppler;micromotion

文中在对微动目标微多普勒分析的基础上，建立了导弹与诱饵的数学模型，采用短时傅里叶变换的方法对回波信号进行微多普勒特征提取，仿真分析了导弹与诱饵的微多普勒特征，通过研究其时频分布特点的差异成功的识别出了真假目标，从而为弹道导弹与重诱饵的识别提供了一个新的有效方法。

The paper firstly examined the mechanical characteristics of wood samples at micron scale, which provided some theoretical basis for the application of wood microtome section to study the in-tree variation of longitudinal mechanical properties of tracheids. In chapter 3, microtension of wood microtome section is for the first time used to explore the in-tree variation of longitudinal MOE of tracheids, meanwhile the size effect of mechanical properties of wood at micron scale is taken into count.

MIRV missile separation rule was built. Preliminary optimum design and optimize separation sequence were carried out. According to target attacking sequence and separation sequence which are preliminarily certain, the optimum separation sequence was determined by building compatibility rule of target attacking sequence and MIRV missile separation sequence.
