Such 3D images of missiles and aircraft will be stored in a database for aircraft and missiles so that it can compare a single angle view of a target spotted by visual or IR or UV or radar in a range of frequencies and this database will help them determine the target.
This means you can put an IIR sensor on an R-37M missile and launch it on a lofted trajectory deep into enemy air space... an ARH sensor would give the missile away to all targets but just using a passive IIR sensor means it can look all the way for targets and perhaps pass back information on what it detects on the way... if it spots a priority target like an F-22 it can turn and attack such a target... perhaps also activating an ARH sensor so DIRCMS wont defeat its optical guidance...
On a Ka-52 or Mi-28NM it can be used in conjunction with the MMW radars so rather than just putting a dot in the display for a detected target it can analyse the returns and identify air and ground targets and display them as the equipment they are.... without needing to zoom in with visible optical systems to positively ID targets and threats...
Missiles like Morfei with an IIR lock on after launch capability will be better able to engage targets of priority without needing assistance.
