Laser Menace Identifying Based on Fuzzy Decision

Identification of laser menaces is an important aspect in laser warning and data disposing. The identifying method has direct effect on its veracity. Based on the fact that technique parameters of laser signal have some fuzzy characters in presenting menaces, a method of identifying laser menaces based on such as fuzzy decision is presented. The fuzziness mathematical models of laser technique parameters laser energy, wavelength, repeat frequency, and fuzzy decision rules library of identifying laser menaces are built, which are set up by using fuzzy decision theory. Professional system of fuzzy decision is designed. Using different kinds of sensors orientation, wavelength, repeat frequency, and in the laser characteristic warning of pulse system, such as laser are acquired. In virtue of the professional system of fuzzy decision, the type of the laser menace is identified. Simulation result shows practical value and method is the most feasible.
