摘要
结合高分辨率傅里叶变换方法,对相邻汽车位置进行了精确定位测量。相比经典谱估计方法,文中所提方法在距离测量过程中避免了繁重的矩阵运算,仅通过迭代运算即可实现精确测量。由于该方法实现简单,仅为现有傅里叶变换的扩展,在车载系统中将会获得实时处理的效果,文末的仿真实验验证了该方法的有效性和实用性。
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.
