Persymmetric Adaptive Detectors in Homogeneous and Partially Homogeneous Environments

Robust GLRT approaches to signal detection in the presence of spatial–temporal uncertainty

“…Fig.1 shows the CFAR properties of the GLRGDD and AMGDD. Precisely, it plots the detection thresholds of the GLRGDD and AMGDD under different ε's and σ 2 n 's for the noise 5 . The results indicate that the detection thresholds are not significantly changed when ε and σ 2 n vary from 0.1 to 1 and 1 to 20, respectively.…”

“…For point-like target detection, a large number of detectors are proposed in the literature, such as Kelly's generalized likelihood ratio test (GLRT) [1], adaptive matched filter (AMF) [2], adaptive coherence estimator (ACE) [3], De Maio's Rao test (DMRao) [4], and the ones recently proposed in [5,6]. For distributed target detection, many famous detection approaches are proposed, such as the generalized AMF (GAMF) [7], generalized adaptive subspace detector (GASD) [7], among others [8][9][10][11][12][13][14].…”

Adaptive polarimetric detection method for target in partially homogeneous background

“…It is an important and common scenario for target detection in non-homogeneous background. Lots of notable research works about this background have been studied [5][6][7][8][9][10][11][12][26][27][28][29]. This paper focuses on the discussion of target detection in partially homogeneous background.…”

On the Recursions of Robust COMET Algorithm for Convexly Structured Shape Matrix

“…Iterative Majorization-Minimization algorithms for the computation of structured CM estimates are developped in [11] and a robust extension of COMET, named RCOMET, has been derived in [13]. The references [8], [9], [12] considered the problem of robust shape matrix estimation with symmetric structures.…”
