首先,通过重新定义样本的类内散布矩阵和类间散布矩阵,提出了一种新的零空间法。
The system was converted to the block controllable form consisting of two parts, one was the range space subsystem and the other was the stable null space subsystem.通过状态变换和去耦合处理将系统转换为块能控标准型,它由值域空间子系统和稳定的零空间子系统组成。
It transforms the double-differential carrier observation equation using null space transformation so that it need not to resolve real-time three-dimensional position parameters.对单个历元的双差载波相位观测方程进行零空间变换,避免了实时变化的三维位置参数求解;
