摘要
在对光纤链路噪声分析和建立的光控相控阵列模型的基础上,通过计算机数值模拟,研究了光路系统噪声对光控阵列方向图和方向性系数及其对阵列接收的线性调频(LFM)雷达信号的脉冲压缩的影响。分析和仿真表明,整个光纤链路的信噪比应大于10dB。
The noises of fiber-optic link is analyzed and the numerical simulation model of optically controlled phased array is built in this paper, Based on the numerical simulation, the noise influences of optical link on pattern and directivity of optically controlled phased array; and on compression of LFM received by an array are discussed. The analyses and simulation results indicate that the total signalnoise ratio （SNR） for an optical link may he above 10 dB.
