ISAR is a form of range-Doppler imaging in which object motion is used to form an image. An account is presently given of the use of laser radar to conduct ambiguity function-like (AFL) and subaperture AFL (SAFL) imaging with all-digital processing. Attention is given to waveform resolution and ambiguities, SAFL image samples, the application of correlation-mixing 'stretch processing', and a plausible design for a heterodyne receiver and generic waveform processor for all-digital stretch processing.
