The interest in the development of radar technologies in automotive systems to increase the drivers' safety standard has motivated our research on a simulator to predict the ultrawideband (UWB) scattering by a generic target discretized with a triangular mesh. Radar systems that employ UWB short pulses permit high space resolution and an efficient transmission of electromagnetic energy. This paper...
A finite difference time domain (FDTD) analysis is applied to investigate capabilities of an ultra-wide band (UWB) radar system to detect a breast tumor. A three-dimensional numerical breast model with a small tumor is used in these investigations. FDTD simulations are carried out assuming a quasi planar incident wave equivalent to that in a planar UWB radar system with a step-frequency synthesized...
In this paper, a pole extraction method using an early-time and late-time responses combined technique is presented. Without the determination of the beginning of the target transient response, the proposed method assumes an ARMA representation to approximate the complete target transient response, and a total least square method is applied to poles extraction. The proposed method is validated using...
