AI Technical Summary
Existing ground-penetrating radar requires repeated scanning when detecting large areas, which is time-consuming and labor-intensive, and the detection accuracy is difficult to guarantee.
The ground-penetrating radar detection method based on MVDR beamforming is adopted. Signals are received simultaneously through a linear antenna array structure. The MVDR beamforming method is used to process the signals of each antenna channel, construct beams, perform scanning and data stitching, obtain a fan-shaped area scanning image, and determine the direction and distance of the target.
It improves the detection efficiency and accuracy of ground-penetrating radar over large areas, enhances signal quality and target detection reliability, suppresses interference signals, and improves target detectability and positioning accuracy.
