多项式变换 meaning in English

polynomial transformation

Bivariate polynomial trans - forms on rational number field
有理域上的二元多项式变换
The experimental results show that the small targets submerged by the large ones can be detected effectively , and better accuracy and shorter computation can be obtained by using the modified rwt than radon - wigner transform
本章首先分析了基于离散多项式变换( discretepolynomial - phasetransform , dpt )参数估计的原理,并将dpt应用于多目标分辨中。
In the forth chapter , the discrete polynomial - phase transform is analyzed and applied to radar multi - target resolving and parameter estimation . a method for symmetrical correlation function to pretreat original signals to suppress additive stationary random noise in lfm signals is proposed . the experimental results show that this method is efficient for reducing noise
利用对称相关函数法对原信号进行预处理,然后再对信号进行离散多项式变换估计信号参数,进行了仿真,仿真结果说明利用这种算法,可以在低信噪比下快速、有效的分辨出多个目标。
