This paper examines the theoretical foundations and signal processing methodologies of , a high-resolution microwave imaging technique . Unlike traditional stripmap SAR, which maintains a fixed antenna angle, spotlight mode continuously steers the antenna to illuminate a single ground patch, significantly increasing the coherent integration time and azimuth resolution. 1. Theoretical Foundation: The Tomographic Paradigm
: Each transmitted pulse provides a segment of the two-dimensional Fourier transform of the target scene's reflectivity.
Spotlight-mode SAR is fundamentally a problem. It can be modeled using the projection-slice theorem from Computerized Axial Tomography (CAT).
