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 …

When we use a traditional adaptive line enhancer (ALE) algorithm to detect an underwater
moving target, there are two disadvantages: the ability to suppress colored Gaussian noise …

It is known that sinusoids generate lines in their spectra, but false lines may appear when
the sinusoids are corrupted by coloured additive noise. In the paper, a higher-order statistics …

This paper describes a technology of multi-dim-small-target detection. Two-dimensional (2-
D) adaptive filtering and multi-dim-small-target segmentation algorithm is suggested to …

This paper describes a technique to identify pixels within a subregion (" chip") of a complex
or detected SAR image which are to be losslessly compressed while the remainder of the …

A novel analysis is presented, which shows that signals consisting of sinusoids plus non-
Gaussian noise have a new signal-to-noise ratio (NSNR) associated with their fourth-order …

This dissertation addresses several research issues pertaining to the compression of
synthetic aperture radar (SAR) imagery: lossless compression and compressibility, lossy …

A new adaptive estimator for direct sequence spread spectrum (DSSS) signals using fourth-
order cumulant based adaptive method is considered. The general higher-order statistics …

Performance of traditional adaptive line enhancer (ALE) in suppressing Gaussian noise is
low and can get worse at low input signal-to-noise ratio (SNR). For greatly overcoming these …
