Orientation Problem of SLAR Imagery

Abstract

This report treats the orientation and restitution problem of SLAR imagery theoretically. The orientation problem is discussed for single SLAR configuration and also for stereo SLAR configuration. For the former, this paper proposed an analytical orientation method constructed on the geometrical basis of SLAR imagery already studied. For the latter, the author developed an orientation technique to calculate the exterior orientation parameters of the antenna for stereo SLAR imageries simultaneously. With this method the analysis of SLAR imagery may be performed three-dimensionally and more accurately than before. In both cases, some functional form, such as polynomials and Fourier's series, is used to model the behaviors of the exterior orientation elements of the antenna along the flight path, as in the analysis of MSS imagery. Linearizing the determination equations for the orientation problem of single SLAR imagery, one obtains error equations for the restitution problem of SLAR imagery. This report introduced simple restitution methods of SLAR imagery for a flat terrain and also for a hilly ground surface, and further, clarified some characteristics.
