Abstract
The smoke interference in passive interference and the basic knowledge of smoke are summarized. The generation and the jamming principle of smoke are analyzed. The distribution function of the smoke particle size and Bill Lambert law of smoke extinction are introduced. The extinction characteristic of the graphite particles to 1.06 μm and 10.6 μm wavelength laser is analyzed. Simulation results show the changing laws of mass extinction coefficient, the transmittance of smoke, which is composed of graphite and copper powder particles, smoke thickness and concentration as particles radius changing.
