recommendations! Published in 2019 at "Remote Sensing Letters"

DOI: 10.1080/2150704x.2019.1601275

Abstract: ABSTRACT Estimators of clutter models parameters based upon higher order moments estimator (HOME) produce usually poor results in particular for low sample sizes. In an attempt to remedy this situation, closed forms of [zlog(z)] and… read more here.

recommendations! Published in 2025 at "IEEE Geoscience and Remote Sensing Letters"

DOI: 10.1109/lgrs.2025.3572579

Abstract: This letter investigates adaptive coherent detectors in compound Gaussian clutter with Nakagami-distributed textures. The maximum a posteriori ratio test (MAPRT) detector is first derived. Using the two-step method, the maximum a posterior (MAP)-Rao/Wald detectors are… read more here.

DOI: 10.1109/tits.2019.2911692

Abstract: This paper proposes an outliers-robust constant false-alarm rate (OR-CFAR) detector of Gaussian clutter based on the truncated-maximum-likelihood estimator (TMLE) in SAR imagery. The proposed method aims at elevating the detection performance in multiple-target environment, where… read more here.

DOI: 10.1109/tvt.2021.3139894

Abstract: This paper investigates the Bayesian detection problem for a moving target that is embedded in a homogeneous Gaussian clutter with an unknown but stochastic covariance matrix for frequency diverse array multiple-input multiple-output (FDA-MIMO) radar. First,… read more here.
