随着微波光子学和相控阵天线技术的广泛应用，因相控阵天线的窄带宽的缺点，目前尚未能很好与传统的电子对抗系统进行融合，本文引入光学延时方式，使得光控相控阵具有宽带的特点，工作频率覆盖2~18 GHz，满足电子对抗领域需求。本文提出的基于宽带光控相控阵的电子对抗系统实现了电扫描、高增益、灵巧波束控制以及小型化低功耗方面的功能，性能进一步提升。并在此系统的基础之上，提出了一种基于宽带光控相控阵的电子对抗方法。
With the wide application of microwave photonics and phased array antenna technology, due to the narrow bandwidth of phased array antenna, it has not been well integrated with the traditional electronic countermeasure system. In this paper, the optical fiber delay method is introduced to make the optical phased array have the characteristics of wideband, and the working frequency covers 2~18GHz, which meets the needs of the field of electronic countermeasure. The electronic countermeasure system based on wideband optical phased array proposed in this paper realizes the functions of electrical scanning, high gain, smart beam control and miniaturization and low power consumption, and the performance is further improved. Based on this system, an electronic countermeasure method based on wideband optically controlled phased array is proposed.
