反射圆 meaning in Chinese

circle of reflexion
reflection circle
son

First , the nonlinear ls problem without constraint is converted to that subjected to inequality constraints by putting constraints on the do as of the received signals and toas of the first arrived signal with geometrically based single - bounce ( gbsb ) statistical channel model and cost - 207 model . then , a penalty function is used in the estimation of ms position
首先，用基于几何结构的单次反射圆模型和cost - 207模型，对期望定位用户的各条多径信号的波达方向和最先到达多径信号的时间进行约束，将传统的解无约束的非线性最小二乘定位问题或近似线性最小二乘定位问题转化为解不等式约束的非线性最小二乘定位问题；然后，用内点罚函数法估计移动台的位置。
