Detection of a rank-one signal with limited training data
Weijian Liu, Zhaojian Zhang, Jun Liu +2
In this paper, we reconsider the problem of detecting a matrix-valued rank-one signal in unknown Gaussian noise, which was previously addressed for the case of sufficient training…
Multichannel adaptive signal detection: Basic theory and literature review
Weijian Liu, Jun Liu, Chengpeng Hao +2
Multichannel adaptive signal detection jointly uses the test and training data to form an adaptive detector, and then make a decision on whether a target exists or not. Remarkably,…
Multichannel signal detection in interference and noise when signal mismatch happens
Weijian Liu, Jun Liu, Yongchan Gao +2
In this paper, we consider the problem of detecting a multichannel signal in interference and noise when signal mismatch happens. We first propose two selective detectors, since th…
Sparsity-Based STAP Design Based on Alternating Direction Method with Gain/Phase Errors
Zhaocheng Yang, Rodrigo C. de Lamare, Weijian Liu
We present a novel sparsity-based space-time adaptive processing (STAP) technique based on the alternating direction method to overcome the severe performance degradation caused by…
