quadratic term

基本解释

Second, through filtering the quadratic term of self term of different components, the relative signal in the LFMs has changed to a sinusoid.
然后用滤除单分量自项二次项的方法使信号成为普通的正弦信号。
This paper expands the non-linear observation function in Taylor's series, takes to the quadratic term and obtains the form of the linear-quadratic term.
本文将非线性观测值函数泰勒级数展开，并取至二次项，得到线性一二次项形式。
On the other hand, it also derives the covariance propagation formula of non-linear function containing quadratic term in matrix form using the matrix theory etc.
另一方面又利用矩阵理论等推导出含有二次项的非线性函数的协方差传播公式的矩阵形式。
