Spotlight-mode SAR is fundamentally a problem. It can be modeled using the projection-slice theorem from Computerized Axial Tomography (CAT).
: High resolution is achieved by synthesizing a large virtual antenna through the platform's motion. Spotlight-Mode Synthetic Aperture Radar: A Sign...
: The tomographic viewpoint allows researchers to account for wavefront curvature , which is critical when the ground patch is large relative to the radar distance. 2. Core Signal Processing Methodologies Spotlight-mode SAR is fundamentally a problem
: Each transmitted pulse provides a segment of the two-dimensional Fourier transform of the target scene's reflectivity. several critical processing steps are required:
To transform raw radar returns into a high-quality image, several critical processing steps are required:
