摘要
本文探讨了FMCW(调频连续波)毫米波体制下目标成像的原理,提出了一种在强杂波背景下恢复目标的二维结构图像的新方法;这种方法既具有强的抑制杂波和噪声能力,又具备超分辨谱估计算法的高分辨特性;所恢复的目标结构图像反映出目标强散射中心的空间分布特征,为解决毫米波反坦克精确末制导过程中强地物杂波背景中地面车辆目标的识别问题提供了一条有效途径。
In this paper,we study the theory of target imaging using FMCW millimeter wave technology,then present a novel method of reconstructing target with two-dimensional image under strong clutter background.This method has the advantage of not only better performance of suppressing clutter and noise but high resolution of super resolution spectrum estimation algorithm.The reconstructed image demonstrates features of spatial distribution of strong target scattering centers and can be applied to land vehicle target discrimination by millimeter wave anti-tank precision guidance.
