Abstract : High resolution image data produced by a SAR is often employed with a monopulse radar to locate fixed ground based target. However, as with any measuring device, there exists some uncertainty or 'error' in target location. By combining the SAR measurements and monopulse radar measurements with measurements from other sensors, we hope to reduce the level of uncertainty in target location. The goal here is to bring together information from SAR and navigation sensors such as global positioning system (GPS) receiver and/or an inertial navigation system (INS). This report focuses on the integration of measurements from a SAR and an INS in a Kalman filter. Many of the points developed here have been presented in other documents. However, the intent of this document is to bring together some of these ideas to implement SAR measurements in a centralized Kalman filter. The goal is to enhance the overall system accuracy.
