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

Spotlight-mode SAR is fundamentally a problem. It can be modeled using the projection-slice theorem from Computerized Axial Tomography (CAT). Spotlight-Mode Synthetic Aperture Radar: A Sign...

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.
