摘要
为适应舰载超视距雷达的复杂电磁环境,提出一种新的测量阵列天线的互阻抗矩阵的方法,通过测量阵列天线各单元的复反射系数来计算天线的互阻抗矩阵.文中给出了测量方法的原理及推导过程,并给出测量系统的原理框图.与其他方法相比,该测量方法简单快捷,易于实现,有很好的实用价值.
For complicated electromagnetic environment of over-the-horigoh-radar, a new method is put forward to measure the mutual resistance matrix of array antenna, which calculates the resistance matrix according to the comex reflecting coefficients from the elements of array antenna. The basic principle, deriving procedure and system ock diagram are presented. Compared with the other methods, this measurement is easier, more quick and feasible in practice.
