In this paper, a new time-frequency analysis method known as the polynomial chirplet
transform (PCT) is developed by extending the conventional chirplet transform (CT). By …

This paper presents one feature-based detector to find sea-surface floating small targets. In
integration time of the order of seconds, target returns exhibit time-frequency (TF) …

Radar target detection in sea clutter is of significance to both the civil and military
applications. With the miniaturization and invisibility of sea targets, Small Floating Targets …

Wind turbine gearboxes generally exhibit complex vibration characteristics due to wide
variations in the operating conditions, and dynamics of the structure coupled with flexible …

海洋物理环境和电磁环境日趋复杂, 海杂波背景下的微弱慢速小目标检测始终是一个研究难点和
重点. 海面小目标的雷达散射截面积小, 回波能量低, 传统基于能量的检测方法存在性能瓶颈 …

In this article, a multifeature detector based on isolation forest (iForest) algorithm is
developed to detect floating small targets in sea clutter. The conventional multifeature …

The ability of the complex continuous wavelet transform (CCWT) to provide also an
estimation of the instantaneous frequency of a signal, parallel to the estimation of the …

This paper addresses the problem of estimating the instantaneous frequency (IF) of
multicomponent radar signals, which are assumed to be frequency-modulated (FM). The …

Intentional jammers broadcasting chirp-style signals present a major threat to the operation
of the global navigation satellite systems (GNSS) receivers. The time-frequency (TF) domain …
