| 摘要: |
| 针对采用频域比相测角的连续波体制雷达，提出了一种基于频域比幅测角的低仰角测量算法。通过分析比相测角与比幅测角的关系，得到可以通过在频域比幅实现连续波雷达角度测量的结论。结合C2算法，实现了连续波雷达低仰角测量算法。通过实际试验结果分析，表明该算法具有优良的抗多径干扰性能。 |

| Abstract: |
| The phase-comparison method in frequency domain is usually used in the angle measurement by the conventional CW radar. Based on amplitude-comparison method in frequency domain, a new algorithm of low-angle measurement by CW radar is proposed. An investigation is made to expose the relationship between phase-comparison method and amplitude-comparison method, with the conclusion that the amplitude-comparison method in frequency domain can be used in the angle measurement by the CW radar. Furthermore, the utility of the C2algorithm is also studied, Additionally, a new algorithm of low-angle measurement of CW radar is given. Experimental results show that the proposed algorithm is effective for tracking the target in low-altitude environment. |
