Abstract

Smoke interference is an economy and practical way of electro-optical countermeasure. In this paper, the mechanism, characteristic, technology and result evaluation of smokes screening laser is discussed to find more effect way of smoke interference. Smoke screen mechanism, characteristic, experiment device and method are discussed experimentally. Especially the smoke screening laser of 0.53μm, 1.06μm and 1.54μm is discussed in detail. On this foundation, an experiment with titanium tetrachloride is designed to detect the effect of smoke screening. Experiment show that titanium tetrachloride and water reaction can generate a great deal of smoke. The smoke is very thick and last out long time. It has good interference effect of laser of 0.53μm, 1.06μm, 1.54μm. But the smoke presents acidic, strong causticity and stimulative. So ammonia was added. In order to improve the interference effect with the parameter change, a great deal experiments were been done at different concentration of ammonia and different dosage of ammonia. The attenuation performance tables of same concentration different dosage and same dosage different concentration were painted. Analyzing these tables, we can get a series of conclusion for smoke screening laser of 0.53μm, 1.06μm, 1.54μm. And also the best parameters are presented for smoke screening.
