Abstract

Multiple beam forming is widely used in modern RADAR system, and it can be accomplished at radar radio frequency by using integrated opto-electronics device and optical fiber distribution and time delay network. This paper describes a receiving system of multiple beams by using integrated opto- electronics device, optical fiber distribution network and optical fiber time delay line. When the opto-electronics switch with controllable extinction ratio and optical microwave phase shifter which can make a good control of phase shifting are applied in this system, the complex weight coefficient can be effectively adjusted, and the adaptive multiple beam forming networks can be established. With the optically controlled multiple beam forming technology, the weight and volume of the system can be reduced and the anti- interference ability and stability of temperature be increased. In addition, the channel numbers can also be increased, which is especially beneficial to large phased arrays system.
