Abstract: Various embodiments of the present invention are directed towards a simulant and method relating to producing a simulant. For example, a simulant of a textured target threat includes a background material associated with a background attenuation, and a texture component(s) dispersed in the background material and associated with a component attenuation and a component characteristic. The component characteristic prevents the component attenuation of the texture component from being homogeneously dispersed throughout the background attenuation of the background material, to cause the simulant to mimic an aspect(s) of an X-ray signature of the textured target threat.

Abstract: In one embodiment, a method for identifying and forming a simulant includes identifying a composition, identifying a plurality of ingredients, the simulant being a combination of the ingredients, identifying for evaluation one or more metrics of the simulant, determining proportions of each of the ingredients by optimizing a quadratic function based on the one or more metrics of the simulant, rendering, via a GUI, a 3D plot that depicts the metrics and a target point specified by the target values of the composition, when the target point is contained within a convex set defined by the identified ingredients, outputting the determined proportions of each of the identified ingredients and, otherwise, receiving user input to adjust the convex set by user selecting and moving the data points of the 3D plot to modify the metrics of the simulant to produce a new 3D plot, and identifying alternative ingredients and/or alternative proportions.

For example, a simulant of a target threat includes at least one component ingredient characterized by a corresponding component loss factor that is essentially zero.
