Three-dimensional imaging can provide more detail information of the target than two-dimensional image, which can be used to identify the target. Thus, it is very useful for detecting in enclosed structures or behind the obstacle. This paper mainly research on the three-dimensional through-the-wall human imaging and introduce an approximate method to calculate the propagation delay when electromagnetic...
Ellipse-cross-localization (ECL) method is presented for TWR location in this paper. The location error is mainly influenced by errors of the wall parameters and the target relative position to antennas. The effect of wall thickness and dielectric constant on TWR localization is analyzed. And the localization accuracy of detection region in different antennas configurations is illustrated by location...
Based on imaging through assumed wall parameters, an approach of target localization for through-the-wall radar in the presence of wall ambiguities is proposed. The target location is estimated by finding the maximum pixel point in composite image which is composed by image sequences corresponding to different assumed wall parameters. The proposed approach is available for target localization with...
The effects of velocity change, refraction and absorption all must be considered for through-the-wall radar, which can displace the target and defocus in imaging. Based on signal propagation model in presence of the wall and the system concept, the relationship is obtained among the transmit signal, target position and the wall transfer function. In this paper, we will present a method to estimate...
A new practical approach to estimate wall parameters with the UWB through-the-wall radar for the moving target localization is presented. By moving two independent monostatic single-antenna radar units to the new standoff positions from the wall, the unknown parameters can be determined; then the exact positions of the moving target are obtained with known wall parameters. The algorithm corrects for...
