摘要
在研究纯方位系统目标运动分析(TMA)的数学模型中,有些存在原理性错误。以两个典型例子,指出了错误所在,并分析了错误的原因。一个是不了解纯方位系统TMA基本原理;另一个是在使用最小二乘法时,对量测函数是待估量线性时常、线性时变、非线性关系或待估量与量测采样点函数关系认识不足,从而导致不能正确使用最小二乘法的错误。
There are foundational mistakes in some mathematic models about TMA in bearings-only system. The article takes two typical cases to illustrate the mistakes and then analyses the reasons for them. One reason is inadequate knowledge about the basic principle of TMA in bearings-only system. The other one is that when utilizing least square method, some technologists can not identify whether the measure function is linear time-constant, linear time-variant or nonlinear, which results in the false usage of least-squares method.
