Concrete Thickness Measurement Model for GPR

The Effect Ricker Wavelet of Duty Cycle Adjustment on GPR Detection Result

“…The Rx antenna is connected to the Rx to process the received signal. In GPR, there are three reflections produced from the transmission of electromagnetic waves symbolized by S1, S2, and S3 which are a reflection provided by the receiving antenna, a reflection of the ground surface, and a reflection of the target [3], respectively. According to a generally accepted terminology, the GPR data is divided into three, namely A-scan, B-scan, and C-scan.…”

“…(1). Where S r , S t , r 1 S t , r 2 S t is a received signal, a transmitted signal, a ground-surface reflection, and a reflection of target [3], respectively.…”

“…VNA is being used to analyze networks with high precision and accuracy where ultra-wideband transmitters and receivers with a frequency range are appropriate for communication technology needs. The transmitter is the VNA port-1, while the receiver is port-2 [3,13]. Fig.…”

“…[1,2]. More detailed functions of GPR are for concrete thickness [3,4], void detection, and corrosion. GPR system include an antenna, amplifier, signal processing, display, and many more.…”

Ground Penetrating Radar Analysis for Detecting Void in Concrete

“…Apart from being applied in the field of natural geological materials, this method has now been applied to other media such as wood, concrete and asphalt. The same methodology can be applied and is non-destructive, such as testing a concrete structure, the application of the depth scale of the object to be measured varies from centimeters to kilometers [3]. The most common form of GPR measurement is the presence of a transmitter and receiver that is moved above the surface of the object to be tested to detect signal reflections from the subsurface features of the test object [4].…”
