Then, the rationality of the weighted area distance is demonstrated and the approach to calculate the base value is deduced. 然后论证了使用加权面积定义距离的合理性并给出了确定距离基准值的方法,为确定各个分量占效应量的比例提供了定量的依据。
It makes use of the RSSI weighted centroid algorithm to obtain an orientation position, uses the RSSI value to compute the overall distance error coefficient, and then takes the method of successive approximation to get the amendment value from the orientation results. 本算法首先利用RSSI加权质心算法获得一初次定位位置。其后,在一个较合理的范围内,引入RSSI值计算总体距离误差系数,采取逐次逼近的方法对初次定位的结果进行修正。
