Line-of-sight Locating algorithm for staring imaging aerial remote sensor

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 multidirections. 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.
