The Optical-Fibre Controlled Delay Line for Broadband Active Phased Antenna Arrays


B.G. Gorshkov, E.S. Kolesnikov

The version of structure of a fiber-optic delay line for control of phase distribution of the broadband active phased antenna arrays on the basis of true time delays is submitted. Key elements of an offered delay line are a tuneble light source and chirped bragg grating. The model of reflection of modulated optical radiation from chirped bragg grating is submitted. The characteristics of a controlled fiber-optic delay line are evaluated.
