Abstract :
A tapped fiber-optics matched delay filter for an RF angle of arrival determination has been constructed and analyzed. The angle-finding characteristics of this four-laser eight-fiber delay line system have been experimentally and theoretically investigated in the 250-750 MHz range. The filter performance was limited by fiber delay time inaccuracies and the unequal frequency responses of the individual laser diodes.
