1. A method for overlaying computer-generated highlights in a display of millimeter wave computer imagery, the method comprising: displaying millimeter wave imagery on a graphical user interface (GUI); displaying visible spectrum images on the graphical user interface, wherein the visible spectrum images are spatially and temporally relative to the millimeter wave imagery; displaying algorithmically created images on the graphical user interface, wherein the algorithmically created images are spatially and temporally relative to the millimeter wave imagery; synchronizing the millimeter wave imagery, the visible spectrum images and the algorithmically created images to a substantially identical time base; and overlaying at least one or more of the visible spectrum images, algorithmically created images, and millimeter wave imagery with a computer generated highlight coinciding with a location of a detected threat.
