Abstract:Many factors such as infrared detecting technology,laser detecting technology ,electron war and so on,make the stealth technology important in the infrared region.It is a difficult problem for heat balance theory to gain the stealth compatibility of infrared and laser in the same wave band.To achieve the compatibility,the conflict demands for infrared and laser stealth materials has to be overcome.Two stealth mechanisms are first introduced separately and a method of compatibility stealth is proposed.On the basis of the mechanism of stealth in infrared and laser,restriction and possibility of the compatibility of the two methods of stealth is analyzed in this paper.
