A technique capable of capturing the dynamics of reservoir fluids in the proximity of production wells would provide enormous benefits to the reservoir management. In fact, monitoring can be used to develop a feedback loop between measurements and control technologies to optimize production. This paper examines the feasibility of a borehole radar tool for near-wellbore imaging. Modeling results...

The imaging radar experiments on Seasat (1978) and on the space shuttles (SIR-A in 1981 and SIR-B in 1984) have resulted in wide interest in the use of spaceborne imaging radars in earth and planetary sciences. The radar sensors provide unique and complementary information about what is acquired with visible and infrared imagers, including subsurface imaging in arid regions,I ,2 allweather obse...

Radar systems using ultra-wideband (UWB) signals have definitive advantages in high range resolution. These are suitable for accurate 3-dimensional (3-D) sensing by rescue robots operating in disaster zone settings, where optical sensing is not applicable because of thick smog or high-density gas. For such applications, where no a priori information of target shape and position is given, an acc...

Abstract. A new incoherent scatter radar called EISCAT 3D is being constructed in northern Scandinavia. It will have the capability to produce volumetric images of ionospheric plasma parameters using aperture synthesis imaging. This study uses current design explore theoretical imaging performance when electron density E region and compares numerical techniques that could be used practice. Of a...
