摘要：这些报告涵盖了开发信号处理结构的进展，该结构利用了环境以及环境引起的信号和噪声变化的现有知识。该研究针对被动声纳探测和分类、连续波 (CW) 和宽带信号、浅水作业、平台安装和分布式系统以及低于 1 kHz 的频率。这项研究的结果预计将产生新的无源声纳探测器和分类器，利用介质变化性和不确定性的知识。结果主要适用于被动处理。然而，活动处理器可以被认为是“与估计海洋相匹配的探测器”。这些结果可能对海军声纳系统应用产生重大影响。
Abstract : The reports cover progress to develop a signal processing structure that exploits available knowledge of the environment and of signal and noise variability induced by the environment. The research is directed toward passive sonar detection and classification, continuous wave (CW) and broadband signals, shallow water operation, both platform-mounted and distributed systems, and frequencies below 1 kHz. The results of this research are expected to lead to new passive sonar detectors and classifiers that take advantage of knowledge of medium variability and uncertainty. The results are mainly applicable to passive processing. However, the active processor can be considered "a detector matched to the estimated ocean." These results could have significant impact on Navy sonar system applications.
