Non-Imaging Determination of Target Orientation via Steered Laser Boresight

摘要

In recent papers the authors have described a non-imaging technique for estimating the shape of remotely illuminated objects. The approach for non-imaging target shape estimation and orientation is model-based. In the absence of pointing errors common to strategic systems, a raster scan by the transmitter would produce the convolution of the expected far-field pattern with the object, providing a starting point for distinguishing targets. The referenced papers show that it is possible to distinguish certain target shapes using a statistical confidence approach based on previous work by the authors. This paper describes a set of shape and orientation χ~2 estimation models for several specific targets, pointing jitters and steered boresight angle. Far-field pattern full-widths-at-half-maximum comparable to those used in recent field experiments are employed.
