PRISM Sensor Modeling

摘要

The Passive Range-angle-angle Imaging with Spectral Measurements (PRISM) sensoris a novel three-dimensional imaging modality conceived by ERIM researchers. The PRISM sensor uses thermal (passive) radiation to form a three-dimensional (range-angle-angle) image. The passive nature of this sensor makes it attractive for imaging applications for which stealth is important. Three dimensional imaging provides a significant increase in information for detection, classification, and general interpretation over the two-dimensional counterpart. The goal of the effort described in this report was to develop, exercise, and evaluate detailed sensor and target signature models. Such models are expected to serve several purposes. First, they serve as an important tool for designing PRISM sensors based on a set of top-level performance requirements. Second, they provide a capability for synthetically generatmg realistic 3-D target signatures, which yields insight into the unique nature of PRISM imagery. Thirdly, they provide a platform for generating PRISM test data for evaluating and processing algorithms, such as phase error correction and automatic target detection and/or recognition algorithms.
