Abstract

In this paper, the optical fiber delay line is designed, in order to eliminate the phased array antenna aperture transition time and aperture effect. The input signal is translated from the electric domain to the optical domain by using the direct modulation mode. The optical fiber delay line is simulated by the simulation software OptiSystem. The results show that the characteristic of beam pointing invariance with changing frequency is realized by time delay compensation. This method can be applied to the phased array antenna. And it can eliminate the effect of the effective aperture phased array.
