一种适用于穿墙雷达成像的墙体补偿算法
A New Wall Compensation Algorithm for Through-the-Wall Radar Imaging
摘要
Abstract
With respect to through-wall-radar imaging,the ambiguities in wall characteristics including thickness and relative permittivity will change the speed and propagation path of electromagnetic wave.These changes will defocus the target image and displace the target away from its true position.A new algorithm is proposed to solve these problems.Though calculating focus delay from the pixel to the antenna accurately, we can correct target image position and focus the target image.Firstly,back-projection imaging algorithm is adopted to obtain the original image.Secondly,the Radon transformation and depth-first-searching algorithm are used to detect the position of wall.Finally,a constraint is got by calculating the distance between the front surface and the back surface of the wall.Under this condition,a couple of assumed wall parameters is adopted to from the focusing target image.关键词
