| 摘 要： | 探讨空间烟云用于外层空间目标红外遮蔽隐身干扰,通过分析烟幕扩散体系的真空及微重力效应,基于扩散定律建立了空间烟云的纯扩散模型.研究结果表明,空间烟云施放后其质量浓度在任意时刻的等值面均为一球面,并且随着球半径的增加在空间连续减少;同时结合辐射在烟云中的传输特性研究,获得了空间烟云有效遮蔽面积及遮蔽时间的估算方法.

| Abstract: | The infrared obscuring stealth application of space cloud in outer space target is discussed. By an- alyzing the vacuum and microgravity effect of smoke diffuse system,the pure diffusion model of space smoke is established based on the diffusion law. Research results show that the mass consistence equality value section of space cloud is sphere surface in whole time after space cloud is discharged,and the mass consistence is decrea- sing with the increasing of the sphere radius. Combining to the transmission characteristic research of radiation in cloud,the estimating method of effective obscuring area and time of the space cloud are obtained. |
