DBF技术是在原来模拟波束形成原理的基础上，引入数字信号处理方法之后建立的一门雷达新技术。数字波束形成就是用数字方式将由于传感器在空间位置不同引入的传播程差导致的相位差进行补偿，从而实现各路信号之间信号同相叠加，使得观测方向能量最大接收，形成特定方向上目标信号检测。-DBF technology is in the original analog beamforming based on principle, after the introduction of digital signal processing method created a new radar technique. Digital beamforming is the way with a number of different positions because of the sensor in space propagation path difference introduced by the phase difference caused by compensation, in order to achieve separate ways with the overlay of the signal between the signals, making the direction of maximum energy observed receiver, the formation of a specific target signal direction detection.
