摘　　要：介绍了一种新的波导裂缝天线设计的方法。该方法根据Elliott的经典理论给出理想状态下的辐射缝隙参数与线源口径分布的数学关系,利用电磁仿真软件提取不同状态下裂缝的参数,拟合得到辐射缝隙电导和裂缝位置长度等物理量间的关系,由此计算出缝隙的各个参量。与传统方法相比,该方法省去了实验测试的环节,提高了设计精度,缩短了设计周期,满足了低副瓣的设计需求。A new method of the waveguide slotted arrays is designed. According to the classical theory of Elliott,the mathematical relationship of the radiating slot parameters and the linear source caliber distribution under an ideal condition is given. The parameters of the slots under different conditions are gained through the electromagnetic simulation software. The simulation data are fitted,and then the relationships of the radiating slot conductance and the location and length of the slots are got. All the parameters of the slots are calculated. Compared with the conventional methods,this method features higher design accuracy and shorter design cycle with the test steps saved,meeting the requirements of the low sidelobe.
