✦ Synopsis

It is shown that typical road surfaces may be considered asrealizations of homogeneous and isotropic two-dimensional Gaussian random processes.Complete description of any suchprocessisprovided by a singleautocorrelation function evaluated from anylongitudinal track, and a single direct spectral density function therefore provides a road surface description which is sufficient for multi-track vehicle response analysis. A new road classification method is proposed whichis based on this function.

The dynamic behavior of a multi-span non-uniform continuous bridge under a moving vehicle is studied by considering the effect of interaction between the structure, the road surface roughness and the vehicle. The bridge is modeled as a multi-span continuous Benoulli-Euler beam with non-uniform cross

## Abstract The statistical analysis of the data obtained from a Monte Carlo simulation of the radar cross section (RCS) of 2‐D targets on ocean rough surfaces is presented. The numerical results of the RCS have been obtained using an accelerated version of the generalized forward–backward method,
