ISAR has emerged as a powerful tool within radar technology, specifically designed for imaging and analyzing moving targets. Unlike conventional radar systems, ISAR leverages the motion of the target itself to create high-resolution images. This work explores the methodology and implementation of ISAR imaging, with a specific emphasis on both simple and complex objects, including cubes, spheres, and aircraft. The study investigates three distinct cases, examining the impact of optimum design procedures, variations in center frequency, and alterations in resolution. The main objective of this paper is to optimize ISAR imaging techniques for diverse moving targets, highlighting the importance of adhering to best practices in radar system design. The study demonstrates the effectiveness of optimum design procedures in achieving high-fidelity ISAR images. The results underscore the critical role of resolution in capturing precise and informative ISAR images, providing valuable insights for future advancements in radar technology and imaging systems for moving targets.
