摘要：
In this paper, we present all interferometry for the direction-of-arrival estimation of ultra-wideband electromagnetic waves. The interaction between the antennas composing the interferometer is calculated by using the finite-difference time-domain (FDTD) method, and taken into account in the analysis. We propose a new signal processing scheme for wideband pulses, and demonstrate its effectiveness using a typical wideband pulse. (C) 2003 Wiley Periodicals, Inc.
