Target Observability for Satellite-Based Sensors.

Abstract

The purpose of this thesis is to discuss the observability of targets moving on or near the earth's surface when viewed from space by an orbiting satellite. A simplified derivation of the satellite's orbital mechanics is undertaken, when taken in conjunction with a description of the target's motion allows for the derivation of a system of relative coordinates. An observability analysis is then performed on the resulting series of nonlinear equations, which in turn forms the basis for the design of a deterministic nonlinear observer and an Extended Kalman Filter to track the target. Keywords include: Nonlinear Observability; Satellite-Based Sensors; Extended Kalman Filter.
