Chapter 8: Scene Representation and Forward Model Variations

Learning Objectives

• Construct point-scatterer, grid-based, and continuous scene representations and understand their tradeoffs
• Derive deterministic channel models for imaging including free-space, multipath, and through-wall propagation
• Apply Swerling models and speckle statistics to characterize target RCS fluctuation
• Identify near-field and wide-angle corrections to the far-field forward model
• Analyze model mismatches from Born approximation breakdown, gridding errors, and calibration
