摘　　要：Dear editor,SAR tomography(TomoSAR)[1]as an adavnced technique forms an elevation aperture along the elevation direction.Therefore,it has the ability of resolving layovers,which are common in urban environments.For the moment,TomoSAR is broadly applied to map the urban areas with existence of large quantities of layovers.
