| 摘 要： | 由于电磁工作环境的恶化和大量射频干扰的存在,在极低的信干噪比(SINR)条件下进行目标检测和信息提取十分困难.对于阵列系统,往往采用自适应数字波束形成(ADBF)技术,来抑制强干扰和方向性干扰对有用信号的影响.给出了数字波束形成器的基本原理及其工程实现.

| Abstract: | Because of the complicated working environment of electromagnetism and a great deal of jamming,target detection and information extraction at very low SINR are very difficult.For array systems,the technique of adaptive digital beam forming(ADBF) is adopted to restrain the strong interfere or directional jamming.The basic theory of the digital beam former and its engineering application are given. |
