提出了一种基于单脉冲系统的新型到达方向估计天线。DOA估计天线由微带天线和Magic-T电路构成，由接收到的射频信号产生Σ和Δ信号。由于馈电电路采用了双面MIC技术，因此该天线结构简单，性能好。本文提出了一种结合放大器和检测器的DOA估计天线，并进行了实验验证。采用射频放大器提高了灵敏度。
We have proposed a novel direction-of-arrival (DOA) estimation antenna based on the mono-pulse system. The DOA estimation antenna is constructed with microstrip antennas and Magic-T circuits which generate Σ and Δ signals from received RF signals. As the Both-sided MIC technology is used for the feed circuit, the proposed antenna has a good performance with simple structure. In this paper, a DOA estimation antenna integrated with amplifiers and detectors is proposed and experimentally evaluated. The sensitivity was improved by using RF amplifiers.
