Abstract :
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 presents three different algorithms, i.e. space quantization, planar wavefront, and spherical wavefront algorithms, to predict the field scattered by a target. In addition to a brief description of the three developed algorithms, a short introduction to the time-domain physical-optics (TDPO) method is provided. Some numerical results are also presented including a comparison of the performances of the three algorithms
