中文摘要:
      受客观条件限制,向阳红09船——蛟龙号载人潜水器的试验母船噪声环境比较恶劣,对水声通信产生了较强的干扰。如何在向阳红09船的这种强、色噪声环境下,提升水声同步信号的检测能力,对提高水声通信的可靠性是非常有帮助的。本文提出统计匹配滤波器这样一种新的检测方法,它通过将接收信号映射到一个生成子空间中进行信号检测,以实现信噪比的提升。通过试验数据分析,验证了该检测算法比传统匹配滤波器有更强的信号检测能力。
英文摘要:
      Restricted by objective conditions, the noise environment of Xiang Yang Hong 09, the mother ship of Jiaolong manned submersibles, is bad which has strong interference with the underwater acoustic communication. Improving the ability of acoustic synchronous signal detection under the strong and color noise environment, it will be very helpful to raise the reliability of underwater acoustic communication. Statistical matched filter in this paper, a new detection method, is introduced. In order to increase the signal to noise ratio, it maps the received signal to a generated subspace for signal detection. Finally, the detection algorithm is verified by experimental data analysis. Comparing to traditional matched filter, statistical matched filter have stronger ability of signal detection.
