| 中文摘要: |
| 数字式声纳的多波束显示是检测目标的重要手段。方位一历程显示是检测微弱信号的有效技术。本文给出了这种利用迹迹相关原理显示方法的理论说明，推导声纳多波束系统输出和输入信噪比的关系。把方位历程显示和传统的方位幅度显示作了比较。理论与实验结果表明，对于弱信号检测，高灰度级的方位历程显示与方位幅度显示比较，有5—7dB的性能改善。 |
| 英文摘要: |
| Multi-beam display is an important means of target detection in digital sonar.Time/bearing display is an effective technique for weak signal detection. The theoretical description of this technique, based on the trace-to-trace correlation effect, is presented in this paper. The relationship between the output of multi-beam system and the input signaLnosie ratio is drived. A comparison of the time/bearing display and the amplitude/bearing dispIay is carried out and illustrated. The theoretical analysis and expetimental result show that the high grade grey level time/bearing display has 5 - 7 dB improvement over the amplitude/bearing display. |
