In this letter, the use of flat-top broad beams is proposed for the improvement of the robustness against direction-of-arrival (DoA) ambiguities in amplitude-monopulse systems, if compared to the conventional use of narrow tilted beams. Oscillations of the monopulse function outside the field-of-view are eliminated, thus suppressing false detections created by signals coming from outside the angular range of interest. Theoretical and experimental results using a modulated leaky-wave antenna, which synthesizes a broad-beam at 15 GHz, confirm this improvement.

使用宽波束模式的振幅单脉冲系统中的歧义度解析

在这封信中,与常规使用窄倾斜光束相比,提出了使用平顶宽光束来提高抗振幅单脉冲系统中到达方向(DoA)模糊性的鲁棒性。消除了视野外的单脉冲函数的振荡,从而抑制了由来自感兴趣的角度范围之外的信号产生的错误检测。使用调制泄漏波天线(在15 GHz频率下合成宽波束)的理论和实验结果证实了这一改进。
