Element‐localized Doppler STAP (Space Time Adaptive Processing) for clutter suppression in automotive forward‐looking RADAR [PDF]

Electronics and Communications in Japan (Part I: Communications), 2006
AbstractIn forward‐looking radars such as automotive radars, it is necessary to suppress the reflected undesirable signal (clutter) from such objects as the ground surface (especially hills), guard rails, and buildings, in order to detect moving targets ahead.

A Training Sample Selection Method With Fusing GIP Statistic and Geographic Information for Airborne Radar

Electronics Letters, Volume 61, Issue 1, January/December 2025.
The method expands sample‐screening dimensions through multidimensional information‐weighted fusion, enabling the selection of more suitable sample sets. Compared with the GIP and knowledge‐aided clutter suppression methods, our proposed method exhibits excellent robustness in different clutter environments and achieves improved clutter‐suppression ...

Local Degree of Freedom of Clutter for Reduced-Dimension Space-Time Adaptive Processing with MIMO Radar

International Journal of Antennas and Propagation, 2018
Degree of freedom (DOF) of clutter in the reduced-dimension (RD) domain, which is called local DOF (LDOF), is of great importance for RD MIMO-STAP (space-time adaptive processing for multiple-input multiple-output radar) algorithms.

An Adaptive Five‐Element Array Antenna Based on Miniaturised Polarisation‐Insensitive Absorptive Metamaterial for Anti‐Jamming Applications

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.
This paper investigates mutual coupling reduction in a five‐element antenna array with constrained aperture dimensions, focusing on polarisation‐insensitive absorptive wall‐type metamaterials for enhanced anti‐jamming performance. The absorptive‐metamaterials‐enhanced adaptive array offers significant advantages for miniaturised platforms and is well ...

Clutter rank estimation for the multistage Wiener filter

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
The authors propose an algorithm that determines the rank of the sea clutter and relates it to the number of stages in the multistage Wiener filter. The algorithm presented is formulated as a model order estimation problem that utilises the minimum description length (MDL).

Sparse Bayesian learning using hierarchical synthesis prior for STAP

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
In this paper, the authors propose a novel SBL algorithm using hierarchical synthesis prior and apply it to STAP technology to improve clutter suppression performance under limited sample conditions. In addition, in order to reduce the computational complexity, the authors propose a local space–time dictionary construction method.

Intent Inference and Syntactic Tracking with GMTI Measurements

, 2011
In conventional target tracking systems, human operators use the estimated target tracks to make higher level inference of the target behaviour/intent. This paper develops syntactic filtering algorithms that assist human operators by extracting spatial ...
