摘　　要：波束合成是阵列信号处理的一个重要内容,随着阵列单元数目的增加,传统电子学信号处理方法面临带宽、速度和功耗的挑战,光学处理技术由于其高度的并行性和超高的带宽,是未来此问题的理想解决方法之一。介绍了波束合成的四种光学处理方法,即纤维光学技术、空间光谱技术、光折变晶体技术和相干光学,分析了它们各自的工作原理和技术特点。Beamformer is an important content of array signal processing. With the increment of the array number, the traditional electrical technology faces the challenges such as bandwidth, speed and power. The optical processing technology is one of ideal solution methods in the future because of its high parallel feature and huge bandwidth. Four optical processing methods used for the beamformer are introduced in this paper, i. e. , fiber optics, spatial spectral technology, optical refractive technology and coherent optics. The respective theory and technology characteristic of them are analyzed.
