A new testing method of shielding effect of single smoke equipment

Smoke emission is an important means to generate quick and wide-range camouflage, in this paper, smoke effect sequence diagrams and effective shielding area were acquired, the formula of M-T was fitted which based on the model of spatial relation between single smoke equipment and detector. The digital image analysis method of dynamic testing of smoke shielding effect was constructed. The dynamic and diffusion characteristics of single smoke equipment was researched. According to the experiment, the variation relationship of smoke area and time was definited, a new testing method of shielding effect of single smoke equipment was formed preliminarily. It laid the theoretical foundation for the shielding effect of multiple smoke equipments and different smoke equipment.
