【摘要】：文中提出了一种基于光纤色散真时延技术的光控相控阵雷达多波束接收网络。该网络制作原理是根据光纤的色散特性,主要由密集波分复用器(DWDM)和光纤延时模块构成。DWDM实现对多通道光合成,多个光开关和光纤延时环组成的光纤延时模块实现对合成的多路光载波进行延时量调节,从而实现波束扫描。依据原理方案,研制了一套16通道光接收、双波束形成网络,实现从-40°到+45°的16个不同波束指向扫描,切换速度≤30μs。暗室测试证明了其波束形成能力。
[Abstract]:In this paper, a multi-beam receiving network of optically controlled phased array radar based on fiber dispersion true delay technique is proposed. The principle of this network is that according to the dispersion characteristics of optical fiber, it is mainly composed of dense wavelength division demultiplexer (DWDM) and optical fiber delay module. DWDM realizes multi-channel optical synthesis. The optical fiber delay module composed of multiple optical switches and optical fiber delay rings realizes the delay adjustment of the synthesized multi-channel optical carrier, so as to realize the beam scanning. According to the principle scheme, a set of 16-channel optical receiving and double beamforming network is developed to realize 16 different beam pointing scanning from-40 掳to 45 掳, and the switching speed is less than 30 渭 s. The darkroom test proves its beamforming ability.
