FMCW Differential Synthetic Aperture Ladar for Turbulence Mitigation

Synthetic Aperture (SA) imaging, including holographic aperture ladar (HAL), synthetic aperture ladar (SAL), and combinations thereof; are promising solutions for long range imaging applications. One of the major difficulties with real-world SA imaging is coherently processing the image information in the presence of atmospheric turbulence. Differential SAL imaging was proposed and patented in ...

Synthetic Aperture Ladar for Tactical Imaging

Understanding how the brain works and reproducing its central capabilities in computers is arguably one of the greatest problems in science and engineering. This project directly contributes to this challenge from both a mathematical and an applied point of view. In particular, we have developed a mathematical description of a family of hierarchical architectures for learning, comprised of a co...

Synthetic Aperture Ladar (SAL): Fundamental Theory, Design Equations for a Satellite System, and Laboratory Demonstration

Three-dimensional differential interference contrast microscopy using synthetic aperture imaging.

We implement differential interference contrast (DIC) microscopy using high-speed synthetic aperture imaging that expands the passband of coherent imaging by a factor of 2.2. For an aperture synthesized coherent image, we apply for the numerical post-processing and obtain a high-contrast DIC image for arbitrary shearing direction and bias retardation. In addition, we obtain images at different ...

The Object Detection Efficiency in Synthetic Aperture Radar Systems

The main purpose of this paper is to develop the method of characteristic functions for calculating the detection characteristics in the case of the object surrounded by rough surfaces. This method is to be implemented in synthetic aperture radar (SAR) systems using optimal resolution algorithms. By applying the specified technique, the expressions have been obtained for the false alarm and cor...
