| 摘 要： | 提出了一种利用时间调制阵列分析入射信号谐波特性的测向方法,针对传统的测向系统较为复杂,信号处理计算量大的问题,文中方法采用两个天线阵元和两个单刀单掷开关,在计算过程中使用了离散傅里叶变换减小了信号处理的计算量,数值仿真验证了该方法的有效性,且具有较好的测向精度。

| Abstract: | A novel direction-finding method based on harmonic analysis by the time-modulated array (TMA) is proposed.Compared with the complex system and higher cost of conventional direction-finding method,the proposed method requires only two antenna elements and two single-pole single-throw switches.The signal processing of the proposed method is concise and its calculation amount concentrates on the discrete Fourier transform (DFT),which reduces the cost of signal processing.Numerical simulations are provided to examine the performance of the proposed method,showing good accuracy. |
