    Abstract: A method for manufacturing nano-sized insensitive high explosive molding powder usable as a booster HE is provided herein. The method preferably involving the steps of dissolving a binder in a liquid and suspending crystalline high explosive to said liquid, grinding that suspension in a bead mill until the crystalline high explosive is nano-sized, and precipitating the binder and crystalline high explosive using a spray dryer to produce granules containing nano-sized crystalline high explosive. The liquid may be water or an organic solvent so long as the binder is highly soluble in the liquid and the crystalline high explosive is generally insoluble in the liquid. A fatty alcohol, water defoaming/dispersant/surfactant agent can be added to the dissolved binder/suspended crystalline high explosive, to aid in the manufacturability.

    Abstract: A precision guided munition with a fin assembly comprising a free spinning hub to which the fins attach addresses the need to roll control a projectile while eliminating the problems of the fin kit. The fin hub, to which the fins are attached, is radially decoupled from the mortar tail boom thus allowing it and the fins to spin freely relative to the body without coupling any of the spin. Advantageously, the need for a bearing between the hub and the tail boom is negated.

    Abstract: A method and system for forming an image comprising at least one processor for performing the following: initializing an N by P image array IO by setting all values to a large number; inputting at least one image frame; randomly selecting and removing a subset of pixel locations from the total number of available pixel locations to form a preliminary image array IC; for each pixel location comparing the complex magnitude of each pixel in the image array IO with the magnitude of the corresponding pixel in image array IC, and if the pixel value in the image array IC is smaller than the corresponding pixel in the image array IO or if the IC value equals 0, then the current pixel value in image array IO is replaced by the pixel value in the image array IC; and repeating for a number of iterations to form an image.
