Waveform Design for Improved Detection of Extended Targets in Sea Clutter

open access: yesSensors, 2019
Adaptive waveform design for cognitive radar in the case of extended target detection under compound-Gaussian (CG) sea clutter is addressed. Based on the CG characteristics of sea clutter, the texture component is employed to characterize the clutter ...

Property Analysis and Suppression Method of Real Measured Sea Spikes

open access: yesLeida xuebao, 2015
In case of high-resolution, low grazing angle, high sea state, and horizontal transmitting, horizontal receiving polarization, the radar returns are strengthened, resulting in sea spikes.

Target detection in high-resolution sea clutter via block-adaptive clutter suppression

open access: yesIET Radar, Sonar and Navigation, 2011
Attentions have been focused on the moving target detection in a high-resolution sea clutter. This study commences with a proposal of median-based estimator to estimate the power spectrum of high-resolution sea clutter by the time series observed in adjacent range cells and time intervals.

A Single-Dataset-Based Pre-Processing Joint Domain Localized Algorithm for Clutter-Suppression in Shipborne High-Frequency Surface-Wave Radar

open access: yesSensors, 2020
Due to the motion of the platform, the spectrum of first-order sea clutter will widen and mask low-velocity targets such as ships in shipborne high-frequency surface-wave radar (HFSWR).

Research on Multi-Domain Dimensionality Reduction Joint Adaptive Processing Method for Range Ambiguous Clutter of FDA-Phase-MIMO Space-Based Early Warning Radar

open access: yesRemote Sensing, 2022
The ground and sea clutter received by space-based early warning radar (SBEWR) has severely range ambiguous characteristics due to its platform location, and the non-stationary factor caused by Earth’s rotation makes the received clutter at different ...

Amplitude suppression of nongaussian sea clutter in a noncoherent bandpass path of the receiver

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2016
The method of non-linear amplitude suppression of radar clutter from a sea surface in a noncoherent band path of the receiver is considered. The model of the most adequate nongaussian a radar clutter from the rough sea surface which envelope is based on ...

A severely range ambiguous clutter suppression method based on multi‐domain cascaded signal processing for space‐based early warning radar

open access: yesIET Radar, Sonar & Navigation, 2023
The non‐stationary clutter phenomenon and the severe range ambiguity make space‐based early warning radar as an intricate model of received ground and sea clutter.

Spreading Sea Clutter Suppression for High-Frequency Hybrid Sky-Surface Wave Radar Using Orthogonal Projection in Spatial–Temporal Domain

open access: yesRemote Sensing
In recent years, the high-frequency hybrid sky-surface wave radar (HSSWR) has been increasingly used for target detection applications. Nevertheless, the specific bistatic system layout and the phase path disturbances induced by the ionospheric ...

Clutter Suppression and Marine Target Detection for Radar Images Based on INet

open access: yesLeida xuebao, 2020
A marine radar device is a major navigation tool for boaters and ships. The images produced by marine radars detect not only hard targets such as ships and coastlines, but also reflections from the sea surface, known as sea clutter.
