During the detection of targets in layered media using ground penetrating radar (GPR), the collected echo data are susceptible to numerous interferences, which in turn impede the accurate interpretation of target information. To effectively remove these interferences and clearly capture target echo signals, novel echo data processing methods are necessary. In this study, we detail the importance of the high-resolution hyperbolic Radon transform in echo data processing and propose a time-scale-corrected high-resolution hyperbolic Radon transform that resolves the limitations of traditional processing methods, such as long processing times and incomplete reconstruction. Based on experimental comparison, the time-scale-corrected high-resolution hyperbolic Radon transform achieved more complete target echo reconstruction within a shorter time. Notably, its application also significantly reduced the time required to identify the sparse solution and effectively extracted the target echo curve, exhibiting superior performance in processing simulated data relative to traditional methods. Therefore, this study provides an effective algorithm and model for GPR applications in complex underground environments that improves the efficiency of target identification. •Proposed time-scale correction high-resolution hyperbolic radon transform method.•Layered medium model adopted to address target extraction interferences.•Hyperbola in echo data reconstructed in short time with a high accuracy.
