研究了扫描速度和扫描发射极位置的联合估计问题。该方法利用天线主梁的均匀旋转运动,将其扫过若干个独立的接收器。基于非线性最小二乘估计(NLS),建立了一个联合估计器。通过几个仿真实例,比较了所提出的估计量与cramer- rao下界(CRLB)的性能。(The joint estimation of scanning velocity and scanning emitter location is studied. The method USES the uniform rotating mot

针对基于双曲线定位的DV-Hop算法中误差项的异方差性引起的定位误差大的问题,提出了一种基于加权双曲线定位的DV-Hop改进算法。算法分析了基于双曲线定位的DV-Hop算法模型中误差项的异方差性,用加权最小二乘法对异方差性进行纠正,对加权最小二乘法中的权值矩阵进行了推导并得到与跳数相关的最佳权值矩阵,使得误差项满足同方差性,所得估计值更加接近最佳线性无偏估计。仿真实验结果表明,所提算法在节点定位精度上较现有的基于双曲线定位的DV-Hop算法都有一定提高。(Aiming at the proble
