We propose a formulation for predicting the cross‐range characteristics of the synthetic aperture radar (SAR) point‐spread function (PSF) for extremely high squints based on the concept of phased array factors. We demonstrate the validity of this approach by comparing theoretical predictions to PSF dimensions extracted from SAR images. The results show that the proposed approach is more robust than the conventional theory for extreme high‐squint scenarios.
