DBF技术及特点DBF是英文“数字波束形成”的缩写。其基本原理是将雷达各天线阵列单元接收到的目标回波的原始射频信号,无失真地变频成中频信号,再变换成数字信号,然后在高速数字波束形成计算机中进行加权和视频数字全成处理,以形成所需的灵活的和高质量的接收波束。与一般的射频模拟波束形成雷达相比,数字波束形成雷达具有以下技术特点: ●扫描快速灵活●运算处理快速●可同时检测、跟踪多个目标
DBF technology and features DBF is the English “digital beamforming” abbreviation. The basic principle is that the original radio frequency signal of the target echo received by each antenna array element of the radar is frequency-converted into an intermediate frequency signal without distortion and then converted into a digital signal, and then weighted and digitized in a high-speed digital beamforming computer Processing to form the required flexible and high quality receive beam. Compared with the general RF analogue beamforming radar, the digital beamforming radar has the following technical features: ● Fast and flexible scanning ● Fast calculation and processing ● Simultaneous detection and tracking of multiple targets
