Synthetic aperture ladar imaging with one-way far-field diffraction

Alaboratory SAL setup produced well-focused SAL images using laser illumination with one-way far-field diffraction.Using 1550 nm fiber laser,the SAL can focus images from target distance of about 2.4 m with azimuth resolution of about 560 μm and range resolution of about 170 μm.High-resolution SAL images are generated by straightforwardly following standard SAL image formation theory,without the aid of phase gradient autofocus (PGA) technique.Detailed results show a typical two-step SAL focusing process and a high resolution image.
