| 摘要: |
| 利用高分辨一维距离像进行目标识别在现代雷达中已成为一个重要的研究课题。本文基于雷达信号设计和互相关接收处理技术,研究了一种利用目标回波,逐次获取一维距离像的方法。与冲激雷达相比,这种方法能显著提高信噪比,并且这个方法的收敛速度快,一般迭代10次以内即达到稳定。 |

| Abstract: |
| Target recognition or identification by using high resolution one-dimensional range profile has become an important research project.In this paper, based on radar signal designing and cross correlation receiving technology,a method for gradually acquiring one-dimensional range profile using target echo is studied. Comparing with impulse radar,this method can greatly improve the signal to noise ratio(SNR),the convergence speed is quick, and iterative times are less than 10. |
| Key words: High resolution radar,One-dimensional range profile,Automatic target recognition,Cross correlation |
