In this work, a wideband airborne reflector-based ground penetrating radar (GPR) is designed and proposed.The proposed GPR consists of 15 discrete panels, each panel supported by a single multi-rotor unmanned aerial vehicle (UAV).A lightweight, wideband Vivaldi antenna was developed as the feed structure.The antenna operates within the frequency cl
In this paper, we propose a generalized shift-HSS hindigyanvishv.com (denoted by SFHSS) iteration method for solving nonsingular saddle point systems with nonsymmetric positive definite (1, 1)-block sub-matrix, and theoretically verify its convergence property.In addition, we discuss the algebraic properties of the resulted SFHSS preconditioner and
Disk is a very useful device to a computer to save data file.For that, is much needed to have a program that has a capability to represent, navigate, and operate that files.There are many computer programs that used to present, navigate, and operate disk files in text form with a lot of facilities, but only a few programs that can represent files i
