Multisensor Fusion Processing for Enhanced Radar Imaging

摘要

This report considers the problem of fusing signature data from a variety of sensors operating over different frequency bands and interrogating a target over diverse angular positions. In particular, the report develops: (1) a framework for fusing signature data for this diverse operating scenario, (2) candidate sensor-fusion algorithms, and (3) a general formulation characterizing the practical problem of cohering data associated with multiband spatially distributed sensors. The report illustrates the formulation by considering numerous examples, transitioning from simple illustrative targets to progressively more difficult and physically realistic targets. The report begins with a constant-amplitude point-scatter model, progresses to three-dimensional targets, and ends by illustrating enhanced image-fusion algorithms applied to static-range data.
