接收信号强度测距法易受室内复杂环境的影响，在许多研究和实际应用中，通常将路径损耗因子作为固定不变常量，增加了系统误差。分析了室内无线信号的传播特性，介绍了对接收信号强度测距模型，推导了最优拟合当前室内环境对数路径损耗模型参数的计算公式，将自主建模的思想引入到基于接收信号强度的测量中进行了可行性探究。

Indoor complex environment has an important effect on received signal strength range based model. In many studies and practical applications, researchers usually make path loss factor as fixed constant, increasing systematic error. Analysis of the characteristics of the indoor wireless signal propagation,introduction on the received signal strength range based models,and the formula derivation of the best fit parameters of the current indoor environment logarithmic path loss model are explored. At last, the article introduces the idea of independent modeling into the received signal strength measurement,and explores the feasibility of the experiment.
