Abstract According to the electromagnetic theory of ultrawideband radio positioning, an ultrawideband spatial spectrum algorithm was proposed. The timereversal operator expressed as multifrequency by using the frequency band segmentation of ultrawideband 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.
