We present an algorithm for fusing data from a constellation of RF sensors detecting cellular emanations with the output of a multi-spectral video tracker to localize and track a target with a specific cell phone. The RF sensors measure the Doppler s

Practical considerations such as cost constrain the aperture size of conventional telescopes, which, combined with atmospheric turbulence effects, even in the presence of adaptive optics, limit achievable angular resolution. Sparse aperture telescope

Publikováno v: Applied optics. 57(30)

Registration of multi-spectral imagery is a critical pre-processing step for applications such as image fusion, but phenomenological differences between spectral bands can lead to significant estimation errors. To develop credible requirements for mu

Wave Front Correction and Post-Detection Image Reconstruction Under Anisoplanatic Conditions with a Scene-Based Wave Front Sensor

Autor: Michael C. Roggemann

Publikováno v: Propagation Through and Characterization of Atmospheric and Oceanic Phenomena.

Improving images measured through anisoplanatic turbulence conditions for horizontal and down-looking imaging applications remains a challenge in image science. We have found that on-axis adaptive optics correction of images measured under anisoplana
