考虑室内环境下存在的非视距和多径传输影响,得到优化的射频参数A和信号传输常数,并基于ZigBee硬件平台进行RSSI测距技术方面的实验,得到基于固定节点的距离比较、高斯滤波和卡尔曼滤波3种数据处理方式的测距精度。实验结果表明,在所选用的3种数据处理方式中,经过卡尔曼滤波处理后的测距精度最高。

Considering non line of sight and multipath transmission effects in indoor environment,gets the optimized RF parameter A and signal transmission constant,makes RSSI ranging technical experiments on the ZigBee hardware platform,obtains the ranging accuracy of three data processing methods for distance model based on fixed node,Gaussian model and Kalman filter model.The experimental results show that the ranging accuracy through Kalman filtering is highest in the three methods.
