Abstract:

The highresolution Fourier transform method is adopted to make precise location estimation of the adjacent vehicles.Compared with the classical spectrum methods,the proposed method avoids the complex matrix computational load during the distance estimation,which can ensure the precise estimation via the iterative procedure.Since this method,which is only the expansion of the Fourier transform,can be easily realized,it can achieve the realprocess effect in the vehiclecarried system.The simulation experiments show the validity of the proposed method.
