Ladar is becoming more prominent due to the maturation of its component technologies,
especially lasers. There are many forms of ladar. There is simple two-dimensional (2-D) …

This paper reviews our studies on coherent and incoherent synthetic-aperture imaging
ladars (SAILs). Using optical diffraction, a systematic theory of side-looking SAIL was …

A variety of synthetic-aperture ladar (SAL) imaging techniques are investigated on a table-
top laboratory setup using an ultra-broad bandwidth (> 3 THz) actively linearized chirp laser …

We present synthetic aperture ladar (SAL) imaging demonstrations where the return-signal
level from the target is near the single-photon level per resolved pixel. Scenes consisting of …

We use convolutional neural networks to recover images optically down-sampled by 6.7×
using coherent aperture synthesis over a 16 camera array. Where conventional …

A principal difficulty of long dwell coherent imaging ladar is its extreme sensitivity to target or
platform motion. This paper describes a motion compensated frequency modulated …

A dual-channel inverse synthetic aperture ladar imaging experimental system based on
wide-pulse binary phase coded signals and its moving target imaging are introduced. The …

Synthetic aperture ladar (SAL) is analogous to the synthetic aperture radar (SAR) but works
at wavelength 104–5 times shorter. SAL has the potential for much finer resolution than …

A long-distance inverse synthetic aperture LADAR (ISAL) imaging experiment outdoors over
1 km for cooperative targets is demonstrated, which gets a two-dimensional high-resolution …

Inverse synthetic aperture ladar (ISAL) can perform high-resolution imaging for satellites.
However, due to the short wavelength of the laser, satellite microvibration will introduce …
