摘　　要：针对泡沫型干扰幕难以同时满足留空时间长和施放距离远这两大关键指标,且易受风、雨等影响的固有不足,提出了舰船泡沫水两用幕(Foam-Water Dual-Purpose Curtain,FWDC)干扰技术.利用舰船水幕系统的现有管系,通过在其水泵后并入特定的泡沫化模块,既可生成泡沫幕笼罩舰船以干扰电磁波的传播,也可直接施放传统水幕.实验结果表明:FWDC可有效干扰多波段电磁波,且气体含量越高时干扰效果越明显(可见光、红外、毫米波与微波在干扰前后的辐射强度之比T最低达18.1%、0.7%,18.6%和28.8%),有效干扰的时间也越长(停止施放1 min后T最低仍可达69.0%、23.0%、66.1%和75.8%),证明了舰船利用FWDC进行多波段干扰这一技术的可行性和高效性.研究结论可为舰船多波段干扰技术的进一步丰富完善以及相应装备的研制提供必要的理论基础和实验依据.A water curtain system based foam-water dual-purpose curtain(FWDC)approach was put forward to solve the problems of conventional foam interfering screens,such as the contradictory indexes of its firing range and floating time,and the influence by wind and rain.FWDC was generated by a foam generator embedded water curtain system and transported through the piping system on warship.Foam curtain and water curtain could be discharged to cover the ship.Results show that FWDC is effective in interfering multi-band electromagnetic waves such as visible light,IR, MMW and CMW,etc.In our experiment,interfering effect of FWDC enhanced with the increase of gas content.Transmitted intensity ratio(T)of visible light,IR,MMW and CMW reach to 18.1%,0.7%,18.6% and 28.8%,and T remains 69.0%,23.0%,66.1% and 75.8% at 1 min after ceased.FWDC was proved to be feasible and effective in multi-wave interference for ship.The research can offer theoretical and experimental basis for improving technique and equipment of interfere foam curtain.
