摘要
数字波束合成技术是通信对抗领域里一项至关重要的技术,通过在数字域对信号幅度和相位进行控制,可以形成多个独立可控的波束,形成波束指向精度高、灵活可变,且理论上不受波束形成数量的限制.本文针对大型相控阵需求,利用波束合成原理,并结合大规模阵列信号同步技术与相控阵幅相校准技术,实现一种可同时产生180个偏馈波束的多波位波束搜索系统.该系统可以利用波束群的实时扫描功能,实现大范围的波束搜索,更快定位目标角度.该系统已在工程上进行应用,并成功执行大型测控任务,取得圆满成功.
Abstract
Digital beam forming technology is a key in the field of communication countermeasures.By controlling the signal amplitude and phase in the digital domain,multiple independent and controllable beams can be formed,with high precision and flex-ibility in beam pointing,and theoretically not limited by the number of beam forming.The article focuses on the requirements of large phased arrays,utilizes the principle of digital beam forming,and combines large-scale arrays signal synchronization technolo-gy and phased arrays amplitude-phase calibration technique,implements a multi-wave position beam search system that can simulta-neously generate 180 biased beams.It can utilize the real-time scanning function of the beam group to achieve large-scale beam search and faster target angle positioning.The system has been applied in engineering and successfully executed a large-scale mea-surement and control task,achieves complete success.
