Research on Grating Delay Line Beamforming Network in Optically Controlled Phased Array
摘要:
本文着重介绍了利用光栅的延迟特性实现光控相控阵雷达天线的波束形成。设计了两种基于光栅的延迟阵列，并分别进行了试验验证，得到光控相控阵的波束连续扫描，试验结果表明这两种延迟阵列各有利弊。综合考虑，方案2优于方案1。
Abstract:
This article focuses on the use of the delay characteristics of the grating to achieve beamforming of an optically controlled phased array radar antenna. Two kinds of grating-based delay arrays are designed and verified by experiments. Finally, beam scanning of the light-controlled phased array is obtained. The test results show that both delay arrays have their advantages and disadvantages. Considering comprehensively, Option 2 is better than Option 1.
