A line-of-sight (LOS) Locating algorithm for staring imaging is presented in this paper. Staring imaging is an imaging mode for aerial remote sensor  which photographs the designated earth-fixed target in muItidirections. Therefore  the details of interesting targets is available. For the target obscured or disguised  its advantage becomes more apparent. This paper proposes the method using two-axis rotation to achieve staring imaging  and establishes the system model and the associated coordinates. Adopting the method of coordinate transformation  the LOS Locating algorithm is constructed  which determines the LOS direction. For the validation of algorithm  Target Geolocation Algorithm is established using Simulink library blocks. Eventually  it proves the feasibility of the LOS Locating algorithm. This article provides a thought of LOS Locating algorithm for staring imaging. The method of coordinate transformation used in this paper can be applied to line-of-sight positioning in other imaging modes. 2010 IEEE.

The magnitude requirement of space target detecting determines that the image of detecting telescope should have several performances: small spots  the wider field of view  small 80% encircled energy diameter and good MTF(Modulation transfer function). So the aperture and field of view of optical system have some demands accordingly. The larger aperture  the more extensive range which the telescope searches. Now most of ground telescopes whose apertures are from 500mm to 1000mm is on-axis optical system  the more energy that telescope collects and higher magnitude the telescope detects  so wide field of view becomes the most importance problem. To obtain large relative aperture and wide field of view  the paper introduces a catadioptric telescope with small aperture aspheric refractive corrector  whose conic surface will be used to remove the aberrations due to large relative aperture and wide field of view. As to the optical system  there is only one aspheric refractive corrector  and it is relatively easy for manufacturing because of its concave figure and normal material. The paper gives the example  and optimizes this optical system with ZEMAX program. And then the paper provides a specific analysis program for testing the aspheric refractive corrector. The aperture of this optical system is 750mm  and its relative aperture is 0.82  and the field of view is 3.6 diameter(diagonal). Its structure is simple and the image quality is also very good. 2009 SPIE.
