V波段单脉冲波导缝隙阵列天线技术

Technology of V-Band Monopulse Waveguide Slots Array

基于V波段设计验证了一款单脉冲波导缝隙阵列天线。提出一体化平面型和差网络设计技术,并与天线集成设计,不仅实现了天线的单脉冲功能,与传统的V波段反射面天线相比,天线保持了高增益、高效率特性,剖面高度有效降低60%以上,有利于减小伺服系统的压力;旁瓣电平降低9dB以上,有利于提高天线的抗干扰性能。分析和测试结果表明,设计方法可行,天线性能优良,适合应用于机载、弹载、导引头等平台。

A type of V-band monopulse waveguide slots array antenna is designed and validated.Planer sum-difference network is presented and integrated with antenna and the function of monopulse.Compared with the conditional V-band reflector antenna,the characteristic of high gain,high efficiency,and 60%reduce of the section height is preserved,but also be beneficial to the servo.The SLL(Side Lobe Level)is improved above 9dB and is beneficial to the antiinterference performance.The results of analysis and measurement show that the method of design is feasible,and the antenna is suitable for airborne,missile and radar seeker platform because of the excellent performance.
