Inverse synthetic aperture radar (ISAR) is different from synthetic aperture radar (SAR) because the former has a larger antenna aperture based on target motion while the radar remains stationary and generates a high-resolution image of moving targets. In this chapter, we will introduce principles related to how ISAR is capable of generating such a high-resolution image of a moving target: ISAR scattering model, ISAR signal waveforms, ISAR image projection plane, point spread function, ISAR image processing, and bistatic ISAR.
