Working on the imaging mode, the dar (digital Array Radar) needs to implement the broadband digital beamforming processing.
数字阵列雷达工作于宽带成像模式下，需要进行宽带数字波束形成。
Compared to common imaging mode, this mode increases SNR of ocean echo by decreasing the bandwidth, then accuracy of fixed position can be improved.
和普通成像模式相比，该模式通过降低带宽的方式来提高回波的信噪比，从而提高了定位精度。
