Study of Sidelobe Suppression Technology Based on Coupled Local Oscillator Arrays

以耦合振荡器阵列作为本振阵列,提出具有旁瓣抑制的接收波束天线阵列扩展结构,推导了其接收波束形成的方向图函数,分析了该接收波束旁瓣抑制技术的可行性,并通过计算机仿真验证了旁瓣抑制技术的理论分析结果,为耦合振荡器阵列应用于天线接收的干扰抑制技术提供了理论基础。

The coupled oscillator arrays are taken as local oscillator arrays,and the augmented receiving array with sidelobe suppression is presented.It deduces the receiving beam direction function,and analyses the feasibility of the sidelobe suppression technology.Lastly,the sidelobe suppression technology and theory analysis result are simulated and validated.It establishes the theoretical foundation for the interference suppression of coupled oscillator arrays at the receiving antenna.
