研究目的
To apply a synthetic aperture radar-based reconstruction technique to focus the unwanted disruptive effects in the two-dimensional ground penetrating radar data using Matched Filter Algorithm (MFA).
研究成果
The MFA achieves a highly successful focused image from raw GPR data, proving to be an effective focusing algorithm. The obtained images of the buried targets are well-focused in their actual positions.
研究不足
The only disadvantage of the algorithm is the long processing time.
1:Experimental Design and Method Selection:
The study employs the Matched Filter Algorithm (MFA) for focusing GPR data. The theoretical model and algorithm are detailed in the paper.
2:Sample Selection and Data Sources:
Real GPR data is gathered from an experimental setup in the laboratory involving buried objects in a wooden pool filled with dry sand.
3:List of Experimental Equipment and Materials:
Agilent E5071B ENA VNA and C-band pyramidal rectangular horn antennas are used for measurements.
4:Experimental Procedures and Operational Workflow:
Measurements are performed in a monostatic and quasi-monostatic configuration, with data collected along a straight path with discrete spatial and frequency points.
5:Data Analysis Methods:
Inverse Fourier Transform (IFT) is applied to the measured data to acquire raw GPR images, followed by MFA for focusing.
