Ground-penetrating radar (GPR) is a widely popular sensing method with broad applications in nondestructive subsurface imaging. This article presents a multistatic GPR for vehicle-mounted roadway and utility monitoring applications that employ several methods to improve performance compared with the state of the art. The proposed system illuminates the subsurface with pseudorandom codes (m-sequences) that have near-ideal autocorrelation properties. As a result, the received signal can be…

TLDR
This paper proposes a broadband, low-noise, and fully-integrated multi-channel receiver for ground-penetrating radar (GPR) applications that provides both low noise and high linearity.
Performance investigation of patch and bow-tie antennas for ground penetrating radar applications
Ground Penetrating Radar (GPR) uses electromagnetic waves to detect objects beneath the earth’s surface. Even though signal processing plays a significant role in GPR performance, the quality of the
Implementation of SAR Radar Imaging Algorithm on GPR and Correction of Its Phase Error in War Mine Detection
TLDR
This paper suggests that due to the characteristics of the Synthetic Aperture Radar in the production of images with the help of electromagnetic waves, the algorithms of this radar be used for imaging from below the surface, and suggests to use phase error correction methods in order to improve the quality of the produced images.
Experimental Comparison of On–Off and All-On Calibration Modes for Beam-Steering Performance of mmWave Phased Array Antenna-in-Package
TLDR
Experimental results show that the on–off calibration mode obtains the same beam-steering performance as the all-on mode for the main beam pattern, though element branch discrepancies obtained in the two modes are different.

TLDR
The design and implementation of a 8 × 8 MIMO-capable impulse-based GPR that transmits m-sequences generated on a low-cost FPGA platform, performs a quadratures transform on the received signal to reduce computation, and implements subsampling to sample the quadrature-converted signals using low-speed ADCs are discussed.
