Adaptive Subspace Signal Detection and Performance Analysis in Nonzero-Mean Clutter
Weijian Liu, Zhenyu Xu, Jun Liu +2
To solve the problem of detecting subspace signals in nonzero-mean clutter, we propose adaptive detectors, based on the strategies of generalized likelihood ratio test (GLRT), Rao…

Bayesian Rao test for distributed target detection in interference and noise with limited training data
Daipeng Xiao, Weijian Liu, Jun Liu +3
This paper has studied the problem of detecting a range-spread target in interference and noise when the number of training data is limited. The interference is located within a ce…
