摘要
根据超宽带无线电技术的电磁波定位原理,提出了一种超宽带空间谱定位算法,结合多重信号分类(Multiple Signal Classification,MUSIC)算法并利用超宽带信号源的频带分割获取多频下的时反算子.仿真结果有效地验证了本文所采用的方法具有良好的定位成像能力.
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.
