This technology uses three different frequency bands to create intensity maps of returned signals.  Signals have traditionally been displayed as raw return data. The intensity of the return is represented by level of brightness. Assignment of a scalar value for intensity is used to determine the brightness of the image.   In this technology, each frequency is given a designated primary color. The intensity of the signal is mapped onto a grid within a volume in the field of view.  Rendering vector images requires multiple numerical values for each voxel/pixel that can be interpreted on a two-dimensional display. If the vector for each voxel has three components it is possible to create color images. Utilizing multiple frequencies enables exploitation of more complex return data enabling truer representation.   Mapping of frequency to color helps the operator distinguish the objects.
