摘要
首先介绍LANDMARC系统室内定位的原理,然后结合"距离-损耗"公式,建立了基于此的模型,在此基础上,对模型参数进行优化,并分别通过引入Z方向矢量和距离噪声系数",作为干扰因子,较真实地模拟了环境变化所产生影响,得到较理想效果,仿真结果表明优化后参数具有很强的抗干扰能力,并能较好为LANDMARC系统的实验与实施提供科学的引导。
The paper firstly introduces the principle of LANDMARC for indoor location,then the model is established based on ＇distance-loss＇ formula,the parameters satisfying error request can be finally obtained by stimulating experiments,and two methods are used to simulate the noise of environment.Simulation results show the parameter adjusted has strong anti-jamming ability,and provides the direction for the experiment and implement of LANDMARC.
