: High resolution is achieved by synthesizing a large virtual antenna through the platform's motion.

To transform raw radar returns into a high-quality image, several critical processing steps are required: Spotlight-Mode Synthetic Aperture Radar: A Sign...

: Each transmitted pulse provides a segment of the two-dimensional Fourier transform of the target scene's reflectivity. : High resolution is achieved by synthesizing a

: 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 Synthetic Aperture Radar: A Sign...

Spotlight-mode SAR is fundamentally a problem. It can be modeled using the projection-slice theorem from Computerized Axial Tomography (CAT).
