Abstract :
Recent work on optical signal distribution and control techniques for phased-array radar is described. Experimental results for millimeter-wave reference signal generation by heterodyning the outputs of two semiconductor lasers are presented. Mixers in which the local oscillator input is an intensity-modulated optical signal are described. The use of these developments, together with other optically controlled devices, in phased-array element architectures is discussed.<>
