ABSTRACT:
Fiber optic delay lines in the form of a modified corporate feed having progressive phase delays and a corporate feed having equal phase delays are used to couple RF modulated light signals to detecting, mixing, amplifying and radiating devices of an active array radar. Different RF signals may be sent over the same fiber delay lines using different light colors (or wavelengths) so that the RF modulated signals in the fiber delay lines do not interact with each other. The RF signals can be put on and taken out of the fiber lines using wavelength division multiplexers, for example. This provides an array with a single optical manifold that allows simultaneous full aperture operation at multiple frequencies and/or beams over a wide operating frequency range.
