Deterministic-aided single dataset STAP method based on sparse recovery in heterogeneous clutter environments

open access: yesEURASIP Journal on Advances in Signal Processing, 2018
Traditional space-time adaptive processing (STAP) usually needs many independent and identically distributed (i.i.d) training datasets for estimating clutter covariance matrix (CCM).

Detection of a signal in linear subspace with bounded mismatch [PDF]

open access: yes, 2006
We consider the problem of detecting a signal of interest in a background of noise with unknown covariance matrix, taking into account a possible mismatch between the actual steering vector and the presumed one.

Optimizing the number of players and training bout durations in soccer small‐sided games: Effects on mood balance and technical performance

open access: yesEuropean Journal of Sport Science, Volume 25, Issue 3, March 2025.
Abstract This study aimed to determine the effects of different bout durations (1 × 12 min, 2 × 6 min and 3 × 4 min) of three‐a‐side (3vs3) and four‐a‐side (4vs4) small sided games (SSGs) with goalkeepers, on the profile of mood state (POMS) scores, and technical performance (percentage of successful passes, percentage of successful tackles, percentage

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

open access: yesInternational 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.
