摘要
与传统模拟相控阵相比,基于数字波束合成技术的数字相控阵在多目标跟踪、抗干扰能力、瞬时动态及杂波抑制等方面具有明显优势,应用前景广泛。根据某数字相控阵项目需求,提出了一种光传输及集中式数字波束合成处理架构,并对该处理架构的可重构处理子阵进行详细设计。基于该处理架构及其可重构处理子阵,可实现任意通道规模数字相控阵的扩展。根据设计结果,完成了可重构处理子阵样机的制造,并进行了试验测试。测试结果表明,设计的数字波束合成处理架构及其可重构处理子阵满足系统要求,可用于该数字相控阵的系统设计。
Compared with traditional analog phased array,digital phased array based on digital beamforming techonology has obvious advantages in multi-target tracking,anti-jamming,instantaneous dynamics and clutter suppression and other aspects,and has a wide application prospect.According to the requirements of a certain digital phased array,a processing architecture with optical transmission and centralized digital beamforming is proposed,and the reconfigurable processing subarray of the processing architecture is designed in detail.Based on the processing architecture and its reconfigurable processing subarray,digital phased array with any number of channels can be expanded.According to the design results,the reconfigurable processing subarray prototype is manufactured and tested.The test results show that the designed digital beamforming processing architecture and its reconfigurable processing subarray meet the system requirements and can be used in system design of the digital phased array.
