1. A digital registration of 3D laser radar data for imaging processing based on selected fiducials using a laser radar system, comprising: raster scanning by a scanner of the laser radar system a target from at least two different positions; using predetermined fiducials to create a digital mapping relating the raster scans from the at least two different positions to each other; defining a three-dimensional linear shift vector for data voxels from the digital mapping; and image mapping using the three-dimensional linear shift vector to improve target-identification of an obscured target.
