摘　　要：以赤磷发烟剂,铜粉和毫米波箔条为组合装药的宽波段干扰弹为研究对象,采用静态测试方法,研究了由磷烟、铜粉、箔条组成的气悬体对3～5 μm、8～14 μm红外辐射和3 mm、8 mm波的衰减性能,实验结果表明该气悬体在3～5 μm、8～14 μm的透过率分别为11%和9%,对3 mm、8 mm波透过率分别为10%和7%,验证了气悬体是一种较好的宽波段干扰材料.各组份不仅继续发挥了单波段良好的衰减作用,而且在一定程度上起到了协同增强的效果,增强了各组份单波段的衰减效果.在目前单一发烟材料尚不具备宽波段干扰的情况下,选择组合方法形成气悬体的方法是可取的技术途径.With taking broadband jamming ammunition composed of red-phosphorus, copper powder and aluminum chaff as research subject, the attenuation performance of aerosol composed of phosphorus, smoke, copper powder and aluminum chaff to infrare（IR） and millimeter wavelength（MMW） was studied by a static testing method. The transmissivities of aerosol are 10 96 and 7 % at 3 mm and 8 mm wavelength, are 11% and 9% at 3-5 μm and 8-14 μm respectively. The results show that the aerosol composed of red-phosphorus, copper powder and aluminum chaff is a better broadband jamming material ; every component can keep and enhance the attenuation capability of single waveband with cooperative enhancing effect; the combined method of forming aerosol is a desirable technique path at the case that the single smoking material doesn＇t possess broadband jamming performance.
