Inverse synthetic aperture radar is an imaging radar in which the radio image is derived by utilizing the Doppler effect produced by change of the target aspect. When the target is accelerated, the resolution in this radar is degraded due to the frequency modulation of the received signal. In order

## Abstract A formulation for groundβpenetrating radar (GPR) imaging using the syntheticβaperture concept is introduced. We show that it is possible to form a 3D image by inverse Fourier transforming the multifrequency, multispatial scattered field. The proposed algorithm for GPR imaging is tested
## Abstract In the classical BβScan ground penetrating radar (GPR) imagery, unprocessed image domain data exhibit undesired hyperbolic effects and therefore have low resolution features. To solve this problem, various focusing or migration techniques have been developed and applied to focus the sca
