  • Feed signal generation for a phased array antenna
    Patent number: 9917651
    Abstract: A feed signal generator (10) for a phased array antenna, comprising: an input (12) to receive an optical spectrum having first and second phase-locked spectral components, respectively having first and second optical frequencies; wavelength selective separator apparatus (14) to separate the optical spectrum into a first optical signal being the first spectral component and a second optical signal being the second spectral component; an optical time delay element (16) to apply a time delay to the first optical signal to form a delayed optical signal; a heterodyning device (20) to heterodyne the delayed optical signal and the second optical signal to generate a feed signal (22) having a power proportional to a product of the amplitudes of the second and delayed optical signals and a phase proportional to the time delay; and optical amplitude control apparatus (18) to set an amplitude of the delayed optical signal such that the product of said amplitudes causes the power of the feed signal to have a preselected
