- Working on the imaging mode, the system adopts broadband signals, thus the conventional narrowband beamforming method is inapplicable. 工作在成像模式时，系统采用具有一定带宽的信号，传统窄带波束形成的方法在宽带相控阵雷达中不再适用。
- The algorithms estimate the DOA of the broadband distributed source fron the secondary diagonal elements of the covariance matrices generated from every frequency domain of the received broadband signals, thus avoiding unwrapping of phases. 该类算法首先将阵列接收的宽带信号变换到频率域，然后对于每个频率形成阵列接收信号协方差阵，最后由该协方差阵的次对角线元素估计宽带分布源的到达角，其主要特点是避免了相位展开。
