Journal ArticleDOI
Photonic beamformer for phased array antennas using a fiber grating prism
TL;DR: In this paper, the authors presented the first measured data on a Bragg reflection grating based fiber-optic prism true time delay processor for transmit/receive phased array beamforming, which takes maximum advantage of component reuse and fully integrates the transmit and receive modes in one efficient hardware compressive topology.
Book
Photonic Aspects of Modern Radar
Henry Zmuda,Edward N. Toughlian +1 more
TL;DR: Assembling a unique blend of expertise from industry, academia, and government, Photonic Aspects of Modern Radar shows the applications of this technology, both in the evolution of today's radar and in future systems.
Journal ArticleDOI
A photonic variable RF delay line for phased array antennas
Edward N. Toughlian,Henry Zmuda +1 more
TL;DR: In this article, a spatially integrated optical system is proposed for control of phased array antennas, which provides mechanical stability essentially eliminating the drift problems associated with freespace optical systems, and can provide high packing density.

Microwave adaptive transversal filter employing variable photonic delay lines
Edward N. Toughlian,Henry Zmuda +1 more
TL;DR: By applying a spatial frequency dependent phase compensation in an optical heterodyning system, a variable rf delay line can be synthesized as mentioned in this paper, which is able to generate continuously variable phased microwave signals over a prescribed frequency band.
Journal ArticleDOI
A deformable mirror-based optical beamforming system for phased array antennas
TL;DR: In this paper, a deformable mirror type spatial light modulator can establish a truly arbitrary continuous optical phasefront which is directly converted to spatial RF phase information by an optical heterodyne system.
