摘要
相控阵天线是雷达技术的重要发展方向之一。随着雷达信号带宽和阵列单元数目的增加,光学实延时技术的采用已成为一种趋势。介绍了一种基于受激光子回波的阵列天线实延时自适应波束合成的光学结构,从理论上详细分析了其工作原理,说明了波束合成的工作过程。
The phased array antenna is one of the important developing directions of rardar technologies. With the increment of the array number and bandwidth. The adopt of optical true time delay is become an trend. An optical architecture of implement true time delay adaptive beamforming based on stimulate photon echoes(SPE) is introduced. The principle is analyzed, and the progress is explained.
