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 mul- tiple signal classification (MUSIC) algorithm. The simulation results effectively prove that the utilized method has better positioning and imaging capability.
