摘　　要：文章设计了一种X频段低副瓣波导窄边缝隙行波阵天线,设计背景是基于船舶交通管理(VTS)雷达系统,作为VTS雷达系统的前端,天线性能的好坏直接影响整个雷达系统。利用电磁仿真软件进行仿真,天线在9.38~9.44 GHz频率范围内电压驻波比小于1.15,增益大于34.5 dB,副瓣电平小于-31.0 dB。This paper designs aX-band nonresonant waveguide narrow edgeslot traveling wave array antenna based on ship traffic management(VTS)radar system.As the front end of VTS radar system,the performance of antennadirectly affects the whole radar system.Using electromagnetic simulation software,the voltage standing wave ratio of antenna in the frequency range of 9.38~9.44 GHz is less than 1.15,the gain is more than 34.5 dB,the sidelobe level is less than-31.0 dB.
