摘要/Abstract

摘要： 基于有限长度、有限电导率圆柱状导体的电磁散射,利用矩量法建立膨胀石墨RCS的计算公式,计算膨胀石墨及石墨干扰弹的平均RCS并测试石墨干扰弹及箔条弹的RCS.结果表明:膨胀石墨对3毫米波具备一定的散射能力,半径为0.12 mm、长度为1.5 mm的单个膨胀石墨粒子平均RCS为0.8676 mm².在干扰材料质量相同的情况下,箔条的RCS是膨胀石墨的7.4倍,膨胀石墨难以对制导武器实施箔条式的诱饵欺骗干扰.

Abstract: To investigate scattering characteristics of expanded graphite in 3 millimeter waves, with method of moment formule of radar cross section (RCS) are established based on electromagnetic scattering of finite length and conductivity cylinder. Average RCS of expanded graphite and its jamming decoy are calcutated. RCS of graphite and chaff jamming decoy are measured through field experiment. It shows that expanded graphite have some scattering ability in 3 millimeter wave. Average RCS of single expanded graphite particle is 0.867 6 mm² as its radius and length are 0.12 mm and 1.5 ram, respectively. RCS of chaff is 7.4 times of expanded graphite as interfering material mass are same. Expanded graphite is difficult to implement in the style of chaff decoy deception jamming on guided weapons.

Key words: expanded graphite, chaff, millimeter wave, radar cross section
