Abstract
A wavelength-coded binary fiberoptic delay line apparatus for time steering of array antennas having a plurality of delay line units serially connected to each other to provide a plurality of delay signals. Signal detecting/converting units which are connected respectively between adjacent delay line units wavelength-code the delay signals passing between the delay line units. The input signal to each delay line unit is separated into two signals one of which is connected to the output of that delay line unit.
