| 摘 要： | 提出了一种对JTIDS信号的高精度测向方法。首先详细分析了JTIDS信号的传输特点，利用Matlab生成的JTIDS信号，然后依据空间谱估计中MUSIC测向算法的特点，将接收到的JTIDS信号按照脉冲分段，对单个脉冲所携带的数据进行处理，最后通过仿真得到不同信噪比环境下多个JTIDS信号方位角和俯仰角的估计精度，验证了该方法的有效性。 |

| Abstract: | A high precision method for DoA(Direction of Arrival) estimation of JTIDS is proposed. The JTIDS signal is generated by Matlab through analysing the transmission characters. Based on the character of MUSIC arithmetic in spatial spectrum estimation, the received JTIDS signal is cut in term of pulse into subsection, and the information in the single pulse is processed. Finally, estimation precision of azimuth and pitching angle of multi-JTIDS signal at different signal-to-noise ratio is obtained by simulation, and the results validate the effectiveness of this method. |
