由于孔径效应和孔径渡越时间的限制，传统的相控阵雷达难以在大扫描角下实现大瞬时带宽，有机聚合物光波导延迟线可解决这一问题。先介绍了有机聚合物光波导延迟线的原理和优点，接着综述了三种延迟线：利用聚酰亚胺制成的4位有机聚合物光波导延迟线，多层结构的有机聚合物光波导延迟线，开关选择的超长有机聚合物光波导延迟线。

Due to the restriction of aperture effect and the aperture delay, it is difficult for a conventional phased array radar to get wide instantaneous band width under wide scan scope. This problem can be solved by using polymeric optical delay lines. In this paper, the theory and merits of polymeric optical delay lines are introduced first, and then three kinds of delay lines are summarized, including 4 bits polymeric optical delay lines using polyimide, polymeric optical delay lines with multiple layers, switchable overlength polymeric optical delay lines.
