| 中文摘要: |
| 本文讨论了主动声纳系统中主动检测结果的数据显示问题。首先介绍传统显示数据缩减的几种算法,在这些基础上,我们提出一种新颖的自适应显示数据缩减算法。此算法利用宽带信号特征和主动检测统计特征,通过分段加权平均并取用子段平均最大值的方法,自适应地缩减待显示数据。仿真结果表明,此算法可以提高数据输出的信息量,减小输出信噪比损失,其性能优于传统的几种显示数据缩减算法,有助于提高人机交互的可靠性,并且算法简单,适于实时实现。 |
| 英文摘要: |
| A new adaptive data reduction algorithm is presented to display large amounts of data on the computer screen of active sonar system. This method adaptively reduces a set of samples to a single value, using the characters of the signal and the statistics of the background. A comparison between this algorithm and conventional ones shows a clear reduction in terms of signal-to-noise loss. This method is easy to apply in the real-time system. |
