针对传统冷烟幕剂比重大、易沉降、多频谱兼容性差等不足, 采用干混法将碳气凝胶和碳纤维混合配药制备了新型多频谱干扰剂.利用烟箱动态系统研究了多频谱干扰剂对红外 (1～3μm、3～5μm、8～14μm) 、10. 6μm激光及毫米波 (3 mm、8 mm) 的衰减性能.结果表明:多频谱干扰剂对红外 (1～3μm、3～5μm、8～14μm) 的透过率均小于5％, 对10. 6μm激光的透过率小于6％, 对3 mm波和8 mm波的最大衰减值分别为10. 73 dB和6. 89 dB.%Aiming at the shortage of traditional smoke agents, such as large ratio, easy settlement and poor compatibility of multi-spectrum, a new multi-frequency interference agent was prepared by mixing the carbon aerogel and carbon fiber. The attenuation performance of multi-spectral interfering agents for infrared (1-3 μm, 3-5 μm, 8-14 μm) 10. 6 μm laser and millimeter wave (3 mm, 8 mm) was studied by using the smoke box dynamic system. The results show that the transmittance of multi-spectral interfering agent to infrared (1-3 μm, 3-5 μm, 8-14 μm) is less than 5％, the transmittance of 10. 6 μm laser is less than 6％, for 3 mm wave and 8 mm wave, the maximum attenuation values are 10. 73 dB and 6. 89 dB, respectively.
