Statistical Analysis and Modeling of Vehicular Radar Cross Section

The individual Radar Cross Section (RCS) of each vehicle is very important for detection, tracking, and classification in automotive radar applications. Apart from these typical radar applications, the bistatic RCS of vehicles can be applied as a scattering model within wireless propagation channel modeling for the evaluation of vehicular communication systems. Therefore, the bistatic RCS of typical vehicles is simulated by ANSYS-HFSS in the communication frequency band of 2.4 GHz. A parametric 3D model of a vehicle regarding its dimensions and shapes was investigated, it can vary from the small compact car to the high-end SUV, including various types of minivans and sedans. The simulated bistatic RCS data are analyzed to extract the statistical information. Based on these information, a statistical RCS model of three different vehicle sizes is derived.
