The future battlefield will be unmanned combat as the leading role, and the unmanned
underwater vehicle (UUV) will play an important role in the future underwater battlefield. In …

Improving the line-spectrum detection capability of a single hydrophone is of great
significance for the passive detection of small underwater platforms. In this paper, we …

The ever increasing technological demand for the DFT computation poses several
challenges both to theory and hardware realization. The design of usual fast Fourier …

Spectral line enhancement and transient interference suppression of underwater objects are
critical issues for passive sonar systems. Conventional approaches for processing spectral …

To address the performance degradation caused by power fluctuations of tones, the multi-
frame coherent integration-based track-before-detect (TBD) method is proposed. In the …

A novel cosine function variable step-size transform domain least mean square (LMS)
algorithm based on matrix rotation (COS-ROTDCT-LMS-DFE) was put forward. Based on the …

In order to detect weak underwater tonals, adaptive line enhancers (ALEs) have been widely
applied in passive sonars. Unfortunately, conventional ALEs cannot perform well amid …

The adaptive line spectrum enhancer is a classic adaptive filter that can be used to filter,
reduce noise, and other processing of signals. In this paper, an adaptive filtering algorithm is …
