摘要： 在应急室内场合下，针对跟踪定位系统，提出一种基于定向信号补偿的免标定室内定位方法。利用2个定向天线发射信号，采集若干个特征点作为训练数据，提取信号特征、中值滤波作为信号补偿，通过加入未标定数据建立定位模型，采用该模型对用户进行定位。实验结果表明，该方法只使用少量接入点和训练数据即可获得较精确的定位结果。

Abstract: In emergency indoor occasion, aiming at the following locating system, this paper proposes a calibration-free indoor location method based on directional signal compensation. This paper uses two directional antenna to send signal, collects several feature point as the training data, extracts signal feature and median filter as a signal compensation. It establishes the localization model by joining not calibration data. The model is applied to the users' positions location. Experimental result shows it can reach high accuracy in the condition of less access points and label data.

Key words: indoor location, signal compensation, emergency occasion, regularization
