38632 利用致密焦面阵列馈源,通过二维来波方向(direction of arrival,DOA)估计算法判别干扰信号的方向,是多波束反射面天线设计中的一个重要环节。 Using dense focal plane array feed, through the two-dimensional wave of direction (DOA) direction of arrivals from, the direction of the discriminant interference signal estimation algorithm, multi-beam reflector antenna is an important part of the design.
38633 由于阵列馈源接收的信号由源信号在反射面焦平面上的电场决定,其阵列流形与常规DOA估计平面阵列的阵列流形不相同; Because of the feed array receiving signals from the source in the reflective surface of the electric field on the focal plane, the array manifold and conventional DOA estimation planar array array manifold is not the same;
38634 焦面场一般是不均匀的,因此选用的阵列单元接收的信号幅度也不相同,部分阵列单元接收的信号会比较微弱;不 Focal plane field is not uniform, so choose the array unit receives the signal amplitude is not the same, part of the array unit receives the signal will be weak;
38635 同的焦面场选用的阵列单元不同,对应的阵列结构也不相同,且其往往是不规则的; Different focal plane field with different array element, the corresponding array structure is not the same, and it is often irregular;
