Author Affiliations +
Experimental results are presented for a nonlinear optical pre-processing filter built and demonstrated to remove transient objects from images sent to a track processor. This filter could be used to enhance track maintenance of point source and small extended objects. Operationally, the nonlinear optical technique accommodates unwanted track image effects such as signal loss, scene saturation, and multiple false signals.
