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.

Terahertz High-resolution Radar Clutter Measurement and Analysis
Leida xuebao, 2015 The clutter characteristics of terahertz high-resolution radar are essential for terahertz radar detection. This study analyzes the traditional clutter probabilistic model and the corresponding parametric estimation methods.

Cross Beam STAP for Nonstationary Clutter Suppression in Airborne Radar [PDF]
International Journal of Antennas and Propagation, 2013 A novel space-time adaptive processing (STAP) method for nonstationary clutter suppression is proposed. The developed method forms a multibeam along the cross line to participate in adaptive processing, which sufficiently utilizes the spatial information

A Sea-Surface-Zoning Method Based on Fractal Characteristics
Sensors, 2022 In this paper, a criterion for sea surface zoning based on the fractal characteristics of disturbances is demonstrated. To improve radar detection performance in heavy-tailed sea clutter, a multitude of sea clutter models and corresponding optimum and ...

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 ...

Clutter modelling and simulation for hypersonic vehicle-borne radar
The Journal of Engineering, 2019 Hypersonic vehicles (HSV) have attracted much attention in recent years because of its military value. The radar system will face more serious clutter problem due to the increasing altitude and velocity.
