| 摘 要： | 子阵级ADBF在相控阵雷达中有重要应用.研究二维子阵级ADBF方法.提出了平面相控阵的子阵级ADBF的信号模型.引入了基于归一化方法的二维子阵级ADBF;通过对子阵输出进行归一化处理,使各子阵的噪声功率相同,从而在无干扰时得到了所希望的静态方向图,因而解决了自适应与非自适应工作模式之间的转换问题;而在存在干扰的情况下,也可对干扰进行有效抑制.该方法与常规的子阵级ADBF相比,明显改善了旁瓣电平.仿真结果证明了其有效性.

| Abstract: | To better apply the ADBF at subarray level to the phased array radar,the two-dimensional ADBF method at subarray level was studied.A signal model of ADBF at subarray level is presented,which is suitable for plane phased array.The normalization method was introduced into the two-dimensional ADBF at subarray level,which normalized the subarray outputs to make the noise power of each subarray be the same,and the desired quiescent pattern was achieved in the absence of jammer,thereby the conversion problem between adaptive and non-adaptive work modes was resolved.The method based on normalization processing can suppress jammer effectively and improve the sidelobe level markedly compared with the conventional method in the presence of jammer.Simulation results indicate the validity of the introduced methods. |
