Microwave breast cancer imaging uses a generalized likelihood ratio test (GLRT), which is a hypothesis testing problem for each voxel, with the null hypothesis representing the tumor-free case.
Since the time correlation of the TSC, a KF-based estimation method is proposed to estimate TSC when the GLRT detection shows the presence of target in this paper.

By replacing the uncertain target amplitude with its MLE, the GLRT detector is then obtained.
Numerical simulations show that the proposed method obtains more precise estimation of DOA using one snapshot compared with the traditional estimation methods such as Capon, APES, and GLRT, based on hundreds of snapshots.

This leads to the idea of an asymptotically equivalent formulation of the Generalized Likelihood Ratio Test (GLRT) known as the RAO hypothesis test.
The Dandawate-Giannakis algorithm can be viewed as the generalized likelihood ratio test (GLRT) for the presence of cyclostationarity.
Alternatively, the widely used invariant detector [19] generalized likelihood ratio test (GLRT) is employed to investigate the resolution performance.
Target detection is one of the core applications of SAR remote sensing and has received considerable attentions in the recent years, such as CFAR method [12-18], the GLRT method [19], the extended fractal-based method [20], the wavelet transform-based method [21], etc..
The proposed method also obtains more precise estimation of DOA angle using one snapshot compared with the traditional estimation methods such as Capon [10], APES [11], and GLRT [12] based on hundreds of snapshots.
