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

open access: yesElectronics 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 ...

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

open access: yesElectronics 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.

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

open access: yesIET 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 ...

Space-Time Adaptive Processing and Jamming

open access: yes
Space-time adaptive processing (STAP) has been a well-established technique, whose basic concept and theory are first put forward by Brennan and Reed. However, it is difficult to implement in the practical system because of the computational complexity ...

Fast ℓ1-regularized space-Time adaptive processing using alternating direction method of multipliers

open access: yes, 2017
Motivated by the sparsity of filter coefficients in full-dimension space-Time adaptive processing (STAP) algorithms, this paper proposes a fast ℓ1-regularized STAP algorithm based on the alternating direction method of multipliers to accelerate the ...
