  • The object's echo time delay often fluctuates in ground-penetrating radar (GPR) application due to the effect of soil.Such fluctuation can hardly be amended using the traditional algorithm with constant velocity to get the optimum image.A new method for precise SAR imaging is proposed by using the lateral variable velocity F-K migration in this paper.The equivalent lateral velocity can be fast estimated by the hyperbolic signatures of the echo.Experimental results show that the proposed method is more effective than the constant velocity migration.

Abstract: The object's echo time delay often fluctuates in ground-penetrating radar (GPR) application due to the effect of soil.Such fluctuation can hardly be amended using the traditional algorithm with constant velocity to get the optimum image.A new method for precise SAR imaging is proposed by using the lateral variable velocity F-K migration in this paper.The equivalent lateral velocity can be fast estimated by the hyperbolic signatures of the echo.Experimental results show that the proposed method is more effective than the constant velocity migration.
