Method of moment/physical optics (MoM/PO) hybridization is applied to predict the effects of an electrically large three-dimensional truncated dielectric radome position on antenna patterns and boresight error. The results showed that boresight error is not zero when antenna located at the center of...

FIG. 6a is a side elevational view of the pair of reticle wheels utilized at the focal plane of the Zoom Projection Optics; FIG. 6b is a side elevational view similar to FIG. 6a, in which the reticle wheels have been rotated to the boresight positions; and ...
optics 322. The collimated signal at this point has a 8 mrad subtense diameter, which equates to a field stop pinhole of 4 mils and an effective focal length of 0.5 inches (fcin FIG. 3). In FIG. 2, one sees the collimated signal exiting the laser and thermal reference source 206 ...
Boresight error allocations of individual optical subassemblies must be verified with test. Boresight tests were performed on several optical subsystems of a military laser required to hold boresight in an airborne military environment. The units tested were fabricated and assembled using the materials ...
