摘　　要：Dear editor,The repeat pass InS AR（interferometric synthetic aperture radar）technique has been successfully applied in topography mapping and terrain motion monitoring by means of Differential InS AR（DInS AR）for many years.There are several factors could influence the observed interferometric coherence,including the system spatial decorrelation,the additive noise,and the scene decorrelation which takes place between the two acquisitions.Dear editor,The repeat pass InS AR（interferometric synthetic aperture radar）technique has been successfully applied in topography mapping and terrain motion monitoring by means of Differential InS AR（DInS AR）for many years.There are several factors could influence the observed interferometric coherence,including the system spatial decorrelation,the additive noise,and the scene decorrelation which takes place between the two acquisitions.
