摘　　要：笔者创新性地提出了一种可快速迭代的波导缝隙阵列天线的设计方法,并据此方法设计了一款高性能的水平极化X波段波导缝隙阵列天线。其工作频带为9.41±0.03GHz,天线增益大于等于35d B;天线水平波束宽度小于等于0.41°,垂直波束宽度小于等于19°;天线近区副瓣(<10°)小于等于-31d B,远区副瓣(>10°)小于等于-35d B;天线电压驻波比小于1.2。此阵列天线具备探测距离远、方位分辨率高、抗干扰能力强等显著优势,可广泛应用于各类船舶交通管理系统(VTS)和海岸警戒雷达系统(CSS)等。In this paper,a new iterative design method of waveguide slot array antenna is proposed,and a high performance horizontally polarized X-band waveguide slot array antenna is designed.Its operating frequency band is 9.41±0.03GHz,the antenna gain is greater than or equal to 35dB;antenna horizontal beam width is less than or equal to 0.41°,vertical beam width is less than or equal to 19°.Area near antenna sidelobe(<10°)is less than or equal to-31dB,area far from antenna sidelobe(>10°)is less than or equal to-35dB,the antenna voltage standing wave ratio is less than 1.2.This array antenna has the advantages of far detection distance,high azimuth resolution and strong anti-interference ability.It can be widely used in various types of vessel traffic service(VTS)and coast guard radar system(CSS).
