Synthesis of Scan- and Frequency-Invariant Low-Sidelobe Tapers for Planar Array Antennas

The impact of the array factor (AF) on the synthesis of a low-sidelobe taper for planar array antennas with a periodic element grid is investigated. A low-sidelobe taper that is synthesized for those far-field directions of the AF belonging to only visible direction, cosine u - v space, can seriously deteriorate with respect to peak sidelobe...

Feasibility of borehole radar measurements to monitor water/steam fronts in EOR applications

A technique capable of capturing the dynamic of the reservoir fluids in the proximity of production wells would provide enormous benefit to the reservoir management; in fact, monitoring can be used to develop a feedback loop between measurements and control technologies to optimize the production. This paper examines the feasibility of a...
