This paper presents a novel information fusion methodology for intelligent terrain analysis. In our application, we define information as terrain characteristics derived from sensor data extracted from on-board spacecraft sensors. The fuzzy-logic construct allows us to represent the terrain characteristics using an easily understandable, linguistic approach. Once derived, these fuzzy terrain characteristics are blended together using a fuzzy rule base to produce a coherent representation of terrain safety. The fused information is then used to autonomously select a safe landing site for spacecraft touchdown. The fuzzy terrain analysis and fusion methodology is explained in detail in this paper. Computer simulation results are provided to show the viability of the approach.
