A 2D processing algorithm for detecting landmines using Ground Penetrating Radar data [PDF]
, 2012 Ground Penetrating Radar(GPR) is one of a number of technologies that have been used to improve landmine detection efficiency. The clutter environment within the first few cm of the soil where landmines are buried, exhibits strong reflections with ...

InSAR Baseline Estimation for Gaofen-3 Real-Time DEM Generation
Sensors, 2018 For Interferometry Synthetic Aperture Radar (InSAR), the normal baseline is one of the main factors that affects the accuracy of the ground elevation. For Gaofen-3 (GF-3) InSAR processing, the poor accuracy of the real-time orbit determination results in

SA-ISAR imaging algorithm based on the gradient signal recovery method
The Journal of Engineering, 2019 As the radar system tends to be complex, obtaining well-focused images with discontinued apertures becomes a challenge. Here, a new sparse aperture inverse synthetic aperture radar (SA-ISAR) imaging approach through the signal recovery method is proposed.
