Even though ground penetrating radar has been well studied and applied by many
researchers for the last couple of decades, the focusing problem in the measured GPR …

Back projection algorithm (BPA) and range migration algorithm (RMA) are two common
approaches for image reconstruction in synthetic aperture radar (SAR) imaging. Imaging is …

In this paper, a novel and complete derivation of the range doppler algorithm (RDA)
formulation is developed for stepped frequency continuous wave (SFCW) synthetic aperture …

Compressed sensing (CS) is a technique which reconstructs an approximated full image
using reduced samples. With the CS technique, the measurement time is reduced and high …

Millimeter-wave (MMW) ground based (GB) synthetic aperture radar (SAR) and inverse SAR
(ISAR) imaging are the powerful tools for the detection of foreign object debris (FOD) and …

In recent years, ground-based micro-deformation monitoring radar has attracted much
attention due to its excellent monitoring capability. By controlling the repeated campaigns of …

In a recent study, we have reported a modified range-Doppler algorithm (RDA) for synthetic
aperture radar (SAR) imaging with stepped-frequency continuous wave (SFCW) …

Stepped-frequency waveforms (SFWs) can use the digital signal processing method to
obtain high-range resolution with relatively narrow instantaneous bandwidth, which has …

Migration is used to collapse “diffractions,” ie, to focus hyperbolic events that appear in the
space-time of a seismic profile—into spots of finite area in the image space. These usually …

During the non-contact geomagnetic detection of pipeline defects, measured signals
generally contain noise, which reduces detection efficiency. Complete ensemble empirical …
