In part II of the passive inverse synthetic radar (P-ISAR) sequence, implications of narrow signal bandwidths on image formation procedures are considered within the previously developed P-ISAR framework of part I. Specifically, the case of single-channel digital television imaging systems is evaluated. For average sized airborne targets illuminated with narrow signal bandwidths, the response is confined to one or two down-range resolution cells, which has significant impact on both inverse synthetic aperture radar (ISAR) resolutions and motion compensation procedures. Simulated results demonstrate that a non-parametric autofocus method, phase gradient algorithm, does not necessarily converge to a properly focused image. Contrast and entropy metrics are also shown to be insufficient for the narrowband imaging case. A parametric Doppler centroid approach is proposed for phase compensation, with resulting imagery closely resembling clairvoyant reconstruction. Finally, the proposed architecture is evaluated in full-scale experiments of commercial air targets, demonstrating the potential for discriminating large and small aircrafts.
