| 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JTI
DS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 pro
posed. The JTIDS signa
l 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 pitchin
g angle of multi-JTIDS signal at different signal-to-noise ratio is obtained
by simulation, and the results validate the effectiveness of this method. |
