Abstract EN
In through-wall radar imaging (TWRI), ambiguities in wall characteristics including the thickness and the relative permittivity will distort the image and shift the imaged target position.
To quickly and accurately estimate the wall parameters, an approach based on a support vector machine (SVM) is proposed.
In TWRI problem, the nonlinearity is embodied in the relationship between backscatter data and the wall parameters, which can be obtained through the SVM training process.
Measurement results reveal that once the training phase is completed, the technique only needs no more than one second to estimate wall parameters with acceptable errors.
Then through-wall images are reconstructed using a back-projection (BP) algorithm by a finite-difference time-domain (FDTD) simulation.
Noiseless and noisy measurements are discussed; the simulation results demonstrate that noisy contamination has little influence on the imaging quality.
Furthermore, the feasibility and the validity are tested by a more realistic situation.
The results show that high-quality and focused images are obtained regardless of the errors in the wall parameter estimates.
