毫米波箔条弹的快速散开及其时频特性

The Fast Spread of Millimeter Wave Foils from a Chaff Despenser and Their Time frequency Domain Characteristics

分析了毫米波箔条弹快速散开过程中箔条偶极子的物理运动特性，及其对回波信号在频域上的影响，同时也探讨了箔条云达到近似稳定状态时的功率谱特性，为毫米波箔条弹的战术运用提供了理论依据与技术上的参考，所得结果丰富了毫米波箔条随机电磁题材的理论基础。

This paper focuses on the physical movement characteristics of millimeter wave foils during their spreading out from a chaff dispenser. The spectral characteristics of a chaff cloud are also taken into account.It proceeds the analysis of the influence on Radar echo waves in time and frequency domain. This paper also provides reference on the tactics of the application of foil dispensers.
