Influence of Optic-Link Phase Characters on Optically Controlled Phased Array

摘要

摘要: 通过光控相控阵列的数值模型和成对回波理论，理论分析并仿真了光路相频特性的波动及其各子阵光路相频特性波动对光控相控阵阵列方向图与脉冲压缩的影响。结果表明光纤链路相频特性对阵列方向图和脉冲压缩存在一定影响，但是由于阵列叠加作用，这种影响可能被削弱。

Abstract: Based on the numerical simulation model of OCPAR and paired-echo theory, the phase fluctuation of optic-link, and the pattern and pulse compression of an array, which are influenced by optic-links phase characteristics, are analyzed theoretically and simulated. The results indicate that the pattern and pulse compression of OCPAR are affected by the phase fluctuation of optic-link somewhat. But the influence may be weakened with the combination function of array.
