Area of Science:

Geophysics
Radar Imaging
Signal Processing

Background:

Traditional subsurface radar imaging uses linear scan trajectories.
Novel applications require nonlinear scans (e.g., breast imaging, wood inspection) due to complex geometries.
Existing methods struggle with data from nonlinear trajectories.

Purpose of the Study:

To propose a novel reconstruction algorithm for subsurface radar data acquired along cylindrical scan trajectories.
To address challenges in subsurface imaging with nonlinear scan paths.
To enhance the accuracy of subsurface radar reconstructions.

Main Methods:

Developed a reconstruction algorithm processing the spectrum of collected radar data.
Algorithm locates spatial origins of target reflections.
Mitigates reflection spreading caused by varying signal travel times along the trajectory.

Main Results:

Successfully tested the algorithm with experimental data from phantoms.
Demonstrated accurate reconstruction in high-contrast subsurface radar scenarios.
Achieved promising results in subsurface imaging applications.

Conclusions:

The proposed algorithm effectively reconstructs subsurface radar data from cylindrical trajectories.
It offers a viable solution for subsurface imaging in complex geometries.
Further research should consider spatial resolution and sampling constraints.
