Abstract:
1. A multi-mode co-boresighted sensor system mounted on a gimbal assembly of an airborne platform, comprising: RF sensor means for sensing RF energy; first optical sensor means for sensing a first type optical energy; second optical sensor means for sensing a second type optical energy; primary mirror assembly having a common collecting aperture for the RF energy and the first and second type optical energy; secondary transmissive/reflective mirror assembly located forward of a focal region of the primary mirror assembly for permitting propagation of RF energy and first type optical energy therethrough to the focal region of the primary mirror assembly and having a reflective surface for reflecting said second type optical energy rearward to said second optical sensor means; said RF sensor means and said first optical sensor means being located at said focal region on an opposite side of the secondary mirror assembly from said second optical sensor means; whereby said RF energy and said first type optical energy simultaneously uses the full collecting aperture of the reflecting surface of the primary mirror assembly along with the second type optical energy as well as sharing a common signal path through said secondary mirror assembly to said RF sensor means and said first optical sensor means.
