Spatial Spectrum Positioning Algorithm for Time Reversal Ultra-wideband System

Abstract

Abstract: According to the electromagnetic theory of ultrawideband radio positioning, an ultrawideband spatial spectrum algorithm was proposed. The timereversal operator expressed as multifrequency by using the frequency band segmentation of ultrawideband signal source was obtained combineing with multiple signal classification (MUSIC) algorithm. The simulation results effectively prove that the utilized method has better positioning and imaging capability.

Key words: ultra-wideband, multiple signal classification (MUSIC), time reversal, location
