DESIGN OF VIRTUAL UNIFORM LINEAR ARRAYS FOR EFFICIENT DIRECTION FINDING

  • 摘要: 在不規(guī)則陣列場合,通過內(nèi)插運(yùn)算構(gòu)造虛擬陣列可以解決高分辨方向估計中的一些問題。本文研究了虛擬均勻線陣的設(shè)計問題,給出了確定虛擬陣元個數(shù)、陣元間隔的方法,并對內(nèi)插矩陣的計算進(jìn)行了討論。
    Abstract: The problem considered in this paper is that of interpolating a virtual uniform linear array from a real two-dimensional array with arbitrary geometry via an interpolation matrix. Central to this problem is how ro place these virtual sensors. It is shown that the virtual uniform linear array should have the same mainlobe beam pattern as the real array over an angular sector of interest. Simulation results are presented to illustrate the application. of virtual array in direction finding.
