    Abstract:

    In order to avoid 2D Photo Detector(PD) array in system design,a research on the theory of time-delay network and beam-forming according to integrated optics based on the microwave optics is performed, in which lens group is utilized to divide and reform the light,and the low-pass character of the photo-detectors is adopted to realize the coherent reforming of Radio Frequency(RF) signals. Errors and their influence on beam-forming are simulated,and the results are compared with the measurements,which reveal that although the signal qualities and the side-lobe levels are decreased,a pattern of four beams in ±30° within 3:1 bandwidth is realized as designed.
