Abstract:
A method of selecting at least one cooperative target from a set of targets, wherein said set of targets includes a subset of cooperative targets and a subset of non-cooperative targets; said method comprising the steps of:generating an optical signal by using an Optical Station; directing said optical signal at each said target from said set of targets; receiving at least one reflected optical signal by said Optical Station; wherein each said reflected optical signal is reflected from one said target from said set of targets; and wherein each said target is marked by said reflection; matching each said reflected optical signal with one said target from said set of targets; creating a database comprising a set of elements, wherein each element of said database includes a distance from said Optical Station to one said target from said set of targets and an amplitude of an actual signal reflected from said one target; post processing said database to create at least one color, wherein each said color is a function of one said element of said database; and creating a color-image of each said target using said at least one color corresponding to said target; wherein said cooperative target has a substantially strong reflectivity in a direction back to said Optical Station; and wherein said non-cooperative target has a substantially weak reflectivity in a direction back to said Optical Station.
