Low Observable Radar Target Detection Method within Sea Clutter Based on Correlation Estimation

Remote Sensing, 2022
The long-time coherent integration can effectively improve the detection ability of radar targets. However, this strategy usually shows poor effect in resisting the sea clutter, which produces difficulties for accurate estimation of sea clutter ...

Fast Dual Trifeature-Based Detection of Small Targets in Sea Clutter by Using Median Normalized Doppler Amplitude Spectra

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
High-resolution sea-surface surveillance radars are designed to find two classes of small targets, low-velocity and floating small targets on the sea surface and low-altitude small targets over the sea surface.

The Dynamic Sea Clutter Simulation of Shore-Based Radar Based on Stokes Waves

Remote Sensing, 2022
The sea clutter model based on the physical sea surface can simulate radar echo at different times and positions and is more suitable for describing dynamic sea clutter than the traditional models based on statistical significance. However, when applying

Bistatic Sea Clutter Suppression Method Based on Compressed Sensing Optimization

Applied Sciences, 2023
In order to reduce the sea clutter interference in the detection of sea surface targets, we propose a bistatic sea clutter suppression method based on compressed sensing optimization in this paper. The proposed method mitigates the interference effect by

Shipborne HFSWR Target Detection in Clutter Regions Based on Multi-Frame TFI Correlation

Remote Sensing, 2022
High-frequency surface wave radar (HFSWR) is an important marine monitoring technology, and this new regime of radar plays an important role in large-scale, continuous early-warning monitoring at sea. In particular, shipborne HFSWR has wider applications

First Measurements with NeXtRAD, a Polarimetric X/L Band Radar Network [PDF]

, 2017
NeXtRAD is a fully polarimetric, X/L Band radar network. It is a development of the older NetRAD system and builds on the experience gained with extensive deployments of NetRAD for sea clutter and target measurements.

Doppler characteristics of sea clutter. [PDF]

, 2010
Doppler radars can distinguish targets from clutter if the target's velocity along the radar line of sight is beyond that of the clutter. Some targets of interest may have a Doppler shift similar to that of clutter. The nature of sea clutter is different in the clutter and exo-clutter regions.
