| Abstract: | The basic composition of optical controlled phased array radar is introduced, and the structure of programmable fiber true time delay lines with multi-channel is proposed. 3-stage FDLs with DWDM and 2× 2 MEMS switches is achieved, and the programmable beam forming network with 8 steering status is demonstrated. The microwave phase shift with 0.16π, 0.32π and 0. 48π for the three stages is measured for 2GHz microwave source. By controlling the switches, 0 - 7 times for the basic phase shift 0. 16π is demonstrated. Finally, the antenna pattern is simulated. |
