One of the main challenges in through-wall imaging (TWI) is the presence of the walls, whose returns tend to obscure the target behind the walls and must be considered and computed in the imaging procedure.
In this paper, a two-step procedure for the through-wall detection is proposed.
Firstly, an effective clutter mitigation method based on singular value decomposition (SVD) is used.
It does not require knowledge of the background scene or rely on accurate modeling and estimation of wall parameters.
Then, TWI problem is cast as a regression one and solved by means of least-squares support vector machine (LS-SVM).
The complex scattering process due to the presence of the walls is automatically included in the nonlinear relationship between the feature vector extracted from the target scattered fields and the position of the target.
The relationship is obtained through a training phase using LS-SVM.
Simulated results show that the proposed approach is effective.
We also analyze the impacts of training samples and signal-to-noise ratio (SNR) on test detection accuracy.
Simulated results reveal that the proposed LS-SVM based approach can provide comparative performances in terms of accuracy, convergence, robustness, and generalization in comparison with the support vector machine (SVM) based approach.
