雾化幕障宽波段消光性能研究

现有宽波段干扰技术普遍存在作用时间太短、干扰波段不够宽等问题,为此研究了新型的雾化幕障干扰技术。研究了其多波段干扰原理、原料配方,并针对可见光、激光、红外、毫米波和厘米波波段光源进行消光性能实验研究。实验结果表明:泡径为2～3 mm厚50 cm的雾化幕障,可完全屏蔽可见光和激光信号,红外透过率小于5%;对毫米波和厘米波信号也能达到良好的遮蔽效果,高效干扰时间在20 min以上,是一种有潜质的宽频无源干扰介质。

Study on broad band extinction performance of atomized screen

A new jamming technology of atomized screen was studied to overcome the shortcomings of existing broad band jamming technology, such as the short acting time and the narrow jamming wave band. The theory of multiband jamming and the formula of atomized screen was introduced. The jamming effect on multiband such as visible light, laser, infrared, millimeter wave radar and centimeter wave radar has been tested. Necessary theory and experimental data were provided for the application of this technology. The experimental results show that visible light and laser could be shielded when the foam diameter of atomized screen was 2-3 mm and the thickness was 50 cm. Under the same conditions, the transmission of infrared was less than 5%, and the good screening effect was achieved on millimeter wave radar and centimeter wave radar. The high efficiency interfering time was above 20 min. The study shows that the new atomized screen was a potential wide frequency passive interfering medium.
