| 摘 要： | 文中通过实地测量数据分析了信号衰减模型的时变特性,提出了一种基于RSSI的定位方法——差圆法。该方法弱化了信号衰减模型的作用从而在一定程度上提高了定位的精确度。仿真分析表明：在测量噪声较小的情况下,差圆法较常用的多边定位法具有更高的定位精度。

| Abstract: | This paper,based on experimental data,analyzes the time varying characteristic of the signal attenuation model.A method named DCA (Difference Circularity Algorithm) based on RSSI is proposed,which could improve the performance by reducing the function of signal attenuation model.Simulation shows that DCA performs better than multilateral algorithm when little noise exists. |
